Here I am Lord.
A Biblical Theology of the Call to Ministry
There are some paths we choose. There are some paths that seem to choose us. It is a moment, buried somewhere in the biography of nearly every great minister, that defies the tidy categories of career development. It is not the moment they graduated seminary, preached their first sermon, or accepted their first call to a congregation. It is an earlier moment, quieter, stranger, more unsettling, when something happened to them that they did not initiate and could not entirely explain. Some heard it as a voice. Others felt it as a weight that would not lift. However they describe it, the meaning is similar: I was called.
We are not, as a culture, well-equipped to take this seriously. We have built an entire civilization around the sovereign self, its preferences, ambitions, and freedom to construct a life of its own choosing. Universities teach self-actualization. Career coaches promise purpose through strategy and self-discovery. Even spiritual life often follows this pattern, as people shop for communities that fit their preferences and curate practices that promise personal growth. The self remains the architect of its own story. The lives that seem to matter most are often those shaped by this reality, people claimed by a purpose they did not invent but could not escape.
What follows is not my analysis. What I intend to offer here is something we desperately need: a serious, searching account of what it means to be called, and why the answer to that question matters not just for ministers, but for all of us trying to understand what we are here to do.
I. What Is a Call?
To speak of a divine call is to make a claim that cuts against the grain of our therapeutic and market-driven age. It is to say that the deepest vocations of human life are not self-generated but received, not manufactured in the workshop of personal ambition but disclosed by a voice that stands over and above our own desires, even while it addresses those desires at their deepest point.
The Hebrew Bible uses several words for this phenomenon. The verb qara, to call, to summon, to name, appears at the most decisive junctures of Israel's story. God calls Abraham from Ur (Genesis 12:1). God calls Moses from the burning bush (Exodus 3:4). God calls Samuel in the night watches of the sanctuary (1 Samuel 3:4). The pattern is consistent: the divine initiative precedes and provokes the human response. It is not that the called person has first sought God with sufficient intensity and thereby earned a hearing. Rather, God speaks, and the world changes.
In the New Testament, the Greek word kaleo carries the same freight. When Jesus walks beside the Sea of Galilee and says to Simon and Andrew, 'Follow me' (Matthew 4:19), the simplicity of the verb conceals a world-altering summons. When Paul reflects on his own vocation, he traces it not to his own religious striving but to divine appointment: 'God, who set me apart from my mother's womb and called me by his grace, was pleased to reveal his Son in me' (Galatians 1:15-16). The call precedes, penetrates, and persists.
We should be clear about what a call is and what it is not. A call is not merely a strong desire to serve, though such desire may accompany it. It is not the accumulated opinion of friends who admire one's gifts, though such affirmation may confirm it. It is not the path of least resistance nor the path of greatest reward. A call is, at its core, a divine address, a word spoken by the living God to a specific person for a specific purpose within the larger purposes of God's redeeming work in the world. And because it is divine in origin, it carries a weight that mere human aspiration cannot sustain under pressure, nor can human ambition fully explain.
II. The Call of Moses: Reluctance and Commission (Exodus 3)
No account of the divine call in scripture is richer in its texture, more honest about its complexity, or more theologically instructive than the call of Moses at the burning bush. Moses is not, at this point in the narrative, a hero awaiting his moment. He is a fugitive, a man who once wielded the power of Pharaoh's court and brought it down with violent, impulsive force, and who has since spent forty years tending sheep in the wilderness of Midian. He is eighty years old. He has, as it were, missed his window.
And yet the God of Abraham, Isaac, and Jacob speaks from a fire that does not consume, but calls:
"Moses! Moses!" And Moses said, "Here I am." (Exodus 3:4)
The call begins with the repetition of the name, a feature we will observe in Samuel's story as well, and one that signals not merely identification but intimate address. God knows this man. God is not summoning an office-holder but a person. And then God discloses the vocation: 'I am sending you to Pharaoh that you may bring my people, the children of Israel, out of Egypt' (Exodus 3:10).
What follows is a masterclass in authentic calling. Moses does not leap at the opportunity. He raises five distinct objections each one a version of the question that every genuinely called person must eventually face: Who am I? What shall I say? What if they don't believe me? I am not eloquent. Please send someone else. God answers each objection not by removing the difficulty but by promising presence: 'I will be with you' (Exodus 3:12). The call is not a guarantee of comfort or competence. It is a guarantee of accompaniment.
Here we encounter the first universal characteristic of a divine call: it is almost always received with some measure of reluctance. The called person does not typically rush forward with confident self-promotion. The call confronts, it disrupts, it addresses a person in their inadequacy and sends them into territory they would not have chosen for themselves. This very reluctance, far from disqualifying the called one, often authenticates the call, for who would voluntarily bear such a burden unless compelled by something greater than personal ambition?
III. The Call of Samuel: Recognizing the Voice (1 Samuel 3)
The boy Samuel ministered before the Lord under Eli the priest. The narrative of 1 Samuel 3 opens with a haunting note: 'The word of the LORD was rare in those days; there was no frequent vision' (1 Samuel 3:1). Israel is in a season of spiritual famine. Eli's sons are corrupt. The priesthood has collapsed under its own moral weight. Into this darkness, God speaks — and he speaks to a child.
"Samuel! Samuel!" And Samuel said, "Speak, for your servant hears." (1 Samuel 3:10)
What is striking about this account is not merely that God calls Samuel but how Samuel learns to hear. Three times the voice comes, and three times Samuel mistakes it for the voice of Eli and runs to the priest. Only when Eli himself discerns what is happening does Samuel learn the proper posture: 'Speak, LORD, for your servant hears.' The call requires not only the voice of God but the formation of a hearing heart, and often that formation is mediated through the community of faith, through older guides who help the younger discern what they are experiencing.
This yields a second universal characteristic of the call: it is rarely self-interpreting. The called one typically needs a community of discernment, a mentor, a Eli, to help them understand that what they are experiencing is not mere ambition, psychological projection, or wishful thinking, but genuine divine address. The call is personal but never merely private. It is confirmed and clarified in relationship.
IV. The Call of Isaiah: Holiness and Commission (Isaiah 6)
If the call of Moses is marked by reluctance and the call of Samuel by gradual recognition, the call of Isaiah is marked by overwhelming encounter with divine holiness. Isaiah 6 is one of the most theologically dense passages in all of scripture. The prophet is granted a vision of the Lord 'sitting upon a throne, high and lifted up,' attended by seraphim who cry out:
"Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory." (Isaiah 6:3)
The response of Isaiah is not enthusiasm but devastation: 'Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!' (Isaiah 6:5). The call to ministry begins not with a strategy session but with a shattering encounter with the holiness of God. The called one must first be undone before they can be remade and sent.
The sequence of Isaiah 6 reveals the structure that undergirds every genuine call: Vision →undoing → cleansing → commissioning → response. Isaiah sees the Lord. He is undone by what he sees. A seraph touches his lips with a burning coal. He is cleansed and forgiven. Then, and only then, does the call go forth:
'Whom shall I send, and who will go for us?' And Isaiah, newly cleansed and reconstituted, responds: 'Here I am! Send me' (Isaiah 6:8).
The third universal characteristic emerges here: the call always involves a moral and spiritual reckoning. No one can stand before the holy God and remain unchanged. Ministry that has not passed through the fires of divine encounter will eventually collapse into mere performance, religious technique in service of personal ego. True calling begins with the recognition that the called one is not sufficient in themselves and must be made sufficient by divine grace.
V. The Call of Jeremiah: Before You Were Born (Jeremiah 1)
The call of Jeremiah introduces a breathtaking dimension of the theology of calling that has profound implications for every minister and every believer: the call precedes the person.
"Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations." (Jeremiah 1:5)
Here the divine call reaches backward beyond birth, beyond the construction of personal identity, beyond anything the called one has done or chosen. Jeremiah's vocation was not contingent on his performance, his spiritual resumé, or his willingness to volunteer. It was embedded in the eternal purposes of God before a single breath had been drawn. This is not fatalism, Jeremiah retains genuine agency, as his subsequent anguished prayers make clear, but it is a declaration that the deepest callings in human life arise from a source that transcends the merely human.
Jeremiah, like Moses, protests his inadequacy: 'Ah, Lord GOD! Behold, I do not know how to speak, for I am only a youth' (Jeremiah 1:6). And God responds, as he responded to Moses, not with a denial of the difficulty but with a promise of divine accompaniment: 'Do not be afraid of them, for I am with you to deliver you' (Jeremiah 1:8). The pattern holds. The call is prior. The commission is certain. The presence is guaranteed.
A fourth characteristic of the call thus emerges: the call has an eternal dimension that relativizes the accidents of biography. The called one does not stumble into ministry by virtue of circumstance or personality. They are known, loved, and appointed by a God who operates in the register of eternity even while addressing persons in the particularity of time.
VI. Jesus and the Calling of the Twelve (Mark 1, Luke 6)
When we arrive at the Gospels, we discover that the calling of the disciples by Jesus recapitulates and intensifies all the patterns we have traced in the Hebrew prophets. The rabbi Jesus does not wait for students to apply. He goes out and summons them, an inversion of the normal Jewish practice of the first century, where students sought out teachers. This reversal is itself theologically significant. The disciples did not choose Jesus; Jesus chose them.
"You did not choose me, but I chose you and appointed you that you should go and bear fruit." (John 15:16)
The accounts in the Synoptics are striking for their economy of description. Jesus passes by, he speaks, 'Follow me', and 'immediately they left their nets and followed him' (Mark 1:18). There is no extended negotiation, no doctrinal examination, no trial period. The call of Jesus carries an authority that demands an immediate response. This is not because discipleship is unreflective but because the One who calls is himself the fulfillment of everything Israel's prophets had anticipated. To hear Jesus call your name is to hear the voice of Israel's God in human flesh.
And yet Jesus does not call twelve identical personalities to identical roles. He calls fishermen and a tax collector, zealots and doubters, those who will lead and those who will betray. The call is personal precisely because the God who calls is personal, not fitting human beings into a generic mold but addressing each one in their particularity and shaping them toward a common purpose.
VII. The Call of Paul: From Persecutor to Apostle (Acts 9)
Of all the calls recorded in the New Testament, none is more dramatic, none more theologically charged, and none more relevant to our understanding of divine initiative, than the call of Saul of Tarsus on the road to Damascus.
Saul was no passive bystander awaiting enlightenment. He was, by his own account, 'a Hebrew of Hebrews,' 'as to zeal, a persecutor of the church,' advancing in Judaism beyond many of his contemporaries (Philippians 3:5-6). He was a man of violent religious conviction, traveling to Damascus with official letters authorizing him to arrest followers of Jesus. And then:
"Suddenly a light from heaven flashed around him. And falling to the ground, he heard a voice saying to him, 'Saul, Saul, why are you persecuting me?'" (Acts 9:3-4)
The parallels with the call of Moses are striking and surely intentional. Moses hears his name called twice from a manifestation of divine presence in fire (Exodus 3:4). Saul hears his name called twice from a manifestation of divine glory in blinding light (Acts 9:4). Moses is sent to confront Pharaoh and liberate Israel. Saul is sent to the Gentiles to open their eyes, 'to turn them from darkness to light and from the power of Satan to God' (Acts 26:18). Moses's call came when he had abandoned any hope of his former vocation. Paul's call came when he was most vigorously pursuing a vocation that was, unknown to him, catastrophically wrong.
Both Moses and Paul resist immediately. Moses offers five objections at the burning bush. Paul, blinded and prostrate, can only ask, 'What shall I do, Lord?' (Acts 22:10). Both are given a specific mission that will define their lives. Both are given companions and mediators, Aaron for Moses, Ananias for Paul. Both suffer immensely for their calling, and both understand that suffering not as evidence of failure but as the very form their faithfulness takes in a broken world.
Paul's understanding of his own call, as it develops in his letters, becomes one of the most theologically sophisticated treatments of calling in all of scripture. He speaks of being 'set apart' before birth, as Jeremiah was (Galatians 1:15). He speaks of receiving his gospel 'not from any human source... but through a revelation of Jesus Christ' (Galatians 1:11-12). He insists that his apostolic authority is not derivative of the Jerusalem church but direct from the risen Lord. And yet he remains in deep solidarity with the wider community of apostles, submitting his gospel to their scrutiny (Galatians 2:2). The call is direct, but it is not self-certifying in isolation.
VIII. The Validation of the Call
At this point a serious pastoral and theological question arises: How do we know whether a call is genuine? The history of the church is littered with the wreckage of self-appointed prophets and charismatic charlatans who confused their own intense desires with divine summons. The question of validation is not peripheral to a theology of calling, it is central to it.
Scripture itself offers a coherent account of how the divine call is authenticated. We may trace it through three great patterns: the validation of Moses, the validation of Elijah, and the validation of Jesus himself.
Moses's call was validated by signs. When he protested that the Israelites would not believe him, God did not merely reassure him, God gave him tools of verification: the staff that became a serpent, the hand that became leprous and was restored, the water that became blood (Exodus 4:1-9). These signs were not magic tricks performed for entertainment. They were divine testimony to the divine commission. They said, in effect: the God who can turn a staff into a serpent is the same God who is turning a shepherd into a deliverer.
Elijah's call was validated in one of the most arresting public spectacles in the whole of the Old Testament. On Mount Carmel, surrounded by 450 prophets of Baal, Elijah called on the God of Israel to vindicate his ministry, and the fire fell (1 Kings 18:38). But the sequence that is often overlooked is the preceding chapter: it is in 1 Kings 17 that the validation begins. Elijah commands that rain will cease, and it does. He is fed by ravens at the brook Cherith. He raises the widow of Zarephath's son from the dead. The pattern is clear: before the great public confrontation of Carmel, there was a series of quieter confirmations, provision, miracle, resurrection, that authenticated the prophet's standing before God and man.
The validation of Jesus as the promised Messiah follows the most comprehensive pattern of all. The Hebrew scriptures are dense with anticipation: the Messiah would be born in Bethlehem (Micah 5:2), born of a virgin (Isaiah 7:14), preceded by a herald crying in the wilderness (Isaiah 40:3), entering Jerusalem on a donkey (Zechariah 9:9), betrayed for thirty pieces of silver (Zechariah 11:12-13), his hands and feet pierced (Psalm 22:16), and rising from the dead (Psalm 16:10). The ministry of Jesus was accompanied by miracles of such quality and character that even his enemies could not deny them, they could only dispute their source (John 11:47-48). And the resurrection, which is the hinge of everything, is the definitive validation: 'declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead' (Romans 1:4).
Paul's call was validated along similar lines. The Damascus road experience was not merely subjective, Ananias was separately commissioned to confirm it (Acts 9:10-17). The early churches received Paul's ministry and observed its fruits. His letters bear the marks of extraordinary theological insight. His apostleship was confirmed by the Jerusalem apostles, who 'gave to me and Barnabas the right hand of fellowship' (Galatians 2:9). He performed 'signs and wonders and mighty works' (2 Corinthians 12:12). And perhaps most powerfully, he endured a catalog of suffering that no sane person would volunteer for without genuine conviction of divine calling: 'Five times I received at the hands of the Jews the forty lashes less one. Three times I was beaten with rods. Once I was stoned. Three times I was shipwrecked' (2 Corinthians 11:24-25).
From this survey, we may identify several consistent marks by which a genuine call is validated: the fruit of transformed lives; the confirmation of the wider community of faith; the alignment of the call with the trajectory of scripture; the willingness to suffer for the call without abandoning it; and, in certain seasons of God's economy, extraordinary signs and wonders that testify to divine appointment. No single one of these is sufficient alone. Together, they form a weight of evidence that reasonable faith can rest upon.
IX. Universal Characteristics of the Call
As we draw these threads together, the biblical theology of calling reveals a consistent pattern across the centuries. These are not cultural accidents or biographical quirks. They are the fingerprints of the God who calls.
First, the call is always an expression of divine initiative. God speaks before the human responds. There is no account in scripture of a person successfully manufacturing their own call through sufficient spiritual intensity. Moses was not meditating on his vocation when the bush burned. Samuel was asleep. Isaiah was in the temple worshipping. Paul was on his way to commit violence. The God who calls is the God who acts first.
Second, the call always involves an element of confrontation with human inadequacy. The called one is not typically the most gifted, the most prepared, or the most willing. Moses stammered. Jeremiah was young. Isaiah was unclean. Paul was a murderer. This pattern is not incidental, it is the point. 'God chose what is weak in the world to shame the strong, so that no human being might boast in the presence of God' (1 Corinthians 1:27-29). The inadequacy of the called one is the space in which divine sufficiency is displayed.
Third, the call is always accompanied by a promise of divine presence. The commission and the companionship are inseparable. 'I will be with you' is the refrain that runs from Exodus to Matthew 28:20: 'And behold, I am with you always, to the end of the age.' The called one is not sent alone. They are sent in the company of the One who sends.
Fourth, the call is always costly. There is no account in scripture of a genuine divine call that led to a comfortable, uncontested life. Moses died outside the land. Samuel was surrounded by faithless kings. Isaiah was (according to tradition) sawn in two. Jeremiah was lowered into a cistern and left to die. Paul was beheaded. Jesus was crucified. The cross is not an interruption to the pattern of faithful calling — it is its highest expression. The call to ministry is a call to share in the sufferings of Christ for the sake of the world he loves.
Fifth, the call is always oriented outward. The called one is not called for their own benefit or spiritual development alone, they are called for others. Moses is called for Israel. Jeremiah is called for the nations. The twelve are called to make disciples of all nations. Paul is called specifically as apostle to the Gentiles. The call to ministry is always a call into service, into the costly, joyful, self-emptying work of bearing God's presence to those who have not yet encountered it.
X. Why the Call Matters
In an age of professional ministry, where seminaries train competent practitioners and churches hire experienced managers, the question of divine calling can seem almost quaint. Surely what matters is skill, character, and commitment. Does the source of the vocation really matter so much? It matters immensely, and for reasons that go to the heart of the gospel.
It matters because ministry is not primarily a service industry but a divine embassy. The minister stands in the place where heaven and earth intersect, proclaiming good news, administering sacraments, binding and loosing, declaring forgiveness, shepherding the flock of God. This is not work that any competent person can do simply by virtue of competence. It requires a sending, an authorization from the One whose embassy this is. 'How are they to preach unless they are sent?' (Romans 10:15). The call is what makes the ministry apostolic in the deepest sense, rooted in the sending purposes of the triune God.
It matters because ministry is inevitably costly, and mere human motivation will not sustain the cost. The minister who enters the vocation for love of influence, love of platform, love of the idea of serving, that minister will find, sooner or later, that the actual work is nothing like the idea. Congregations are complicated. Suffering is relentless. Critics are vocal. Successes are rare and often ambiguous. What sustains a minister through decades of faithful, unspectacular service is not enthusiasm, enthusiasm fades, but conviction: I have been sent. I did not choose this. I cannot un-choose it. Paul put it memorably: 'Woe to me if I do not preach the gospel!' (1 Corinthians 9:16). The call is the ballast in the storm.
It matters, too, because the stakes of ministry are eternal. The minister handles the Word of God, the bread of life, the cup of salvation. Flippancy about authorization in this realm would be catastrophic. The biblical tradition is not nervous about distinguishing genuine prophets from false ones, genuine apostles from self-appointed pretenders. The question 'Has God truly called this person?' is not an institutional bureaucratic question, it is a question about the integrity of the gospel itself.
And finally, the call matters because it locates the minister's identity not in their success or failure but in their relationship with the One who called them. The called minister is not primarily a professional whose worth is measured by outcomes. They are a person addressed by name, 'Moses! Moses!', 'Samuel! Samuel!', 'Saul, Saul!', by a God who knows them intimately and loves them unconditionally and sends them precisely because he trusts them with a portion of his own redemptive work in the world.
Conclusion
The call to ministry is one of the most ancient, most contested, and most life-shaping realities in the biblical narrative. From the burning bush to the Damascus road, the pattern holds: God speaks, the human is addressed, inadequacy is confronted, presence is promised, mission is given, validation follows, and the called one goes, imperfectly, courageously, in the company of the One who sent them.
The church in every generation must recover this understanding. Not because institution-building is unimportant, or because spiritual gifts and theological training are to be despised, they are gifts of the same God who calls, but because without the undergirding reality of divine vocation, ministry becomes merely a career, and the church becomes merely an organization.
The gospel deserves better. The world needs more. And the God who called Moses from the backside of the desert, who called a boy named Samuel in the midnight watches, who called Isaiah from the debris of his self-understanding, who called Paul from the road to violence into the road to Rome, that God is still calling. The burning bush still burns. The voice still speaks. The question is whether we have ears to hear it. "Here I am. Send me." (Isaiah 6:8)
This is a great read. Amen. The call of God has never gone silent; only our willingness to listen sometimes fades.
