Recovering Teleological Purpose in Christian Witness

There is a question lurking beneath nearly every significant conversation you will ever have with a non-Christian neighbor, colleague, or friend. It rarely gets asked out loud. People don’t usually pause mid-coffee and say, ‘By the way—why do you think any of this matters?’ But it is always there, threading through discussions about work, relationships, suffering, ambition, and death. The question is deceptively simple: What is the purpose of human existence?

This is the terrain of teleology—the philosophical and theological study of purpose, ends, and meaning. And for the Christian witness, it is among the most generative entry points for authentic, dialogical gospel conversation in the twenty-first century. When you learn to hear the teleological hunger embedded in the stories people tell about their lives, you gain extraordinary capacity to connect the gospel to what people are actually searching for—not merely to a list of doctrines they are supposed to believe.

This post is part of Missional University’s Worldview in Gospel Witness series, which equips followers of Christ to engage meaningfully with the diverse worldviews of our pluralistic world. We are not primarily training church programs here. We are equipping individual disciples—you—to be the kind of person whose conversational witness opens windows to transcendent meaning in a culture that has tried, and failed, to manufacture it without God.

 

The Preacher Who Tried to Answer the Question Without God

The book of Ecclesiastes is one of the most theologically honest documents in the entire biblical canon. Qohelet, the Preacher, launches an extended experiment in the pursuit of meaning ‘under the sun’—a phrase that signals the methodological boundaries of his inquiry. He tries wisdom, pleasure, achievement, wealth, labor, and relationship. He brings to his search unparalleled resources and relentless intellectual rigor. The verdict is devastating: ‘Vanity of vanities, all is vanity‘ (Ecclesiastes 1:2, ESV).

What Qohelet is demonstrating is not nihilism. He is staging a critique—a deliberate reductio ad absurdum of every secular attempt to ground ultimate meaning in created things. The sun rises, the rivers run to the sea, generations pass, and nothing under the sun carries the weight of final significance. The honest conclusion of a purely immanent worldview is exactly the existential vacuum that Viktor Frankl documented in his survivors of Nazi concentration camps: human beings can endure almost any suffering if they can find a reason for it, but a life without transcendent purpose corrodes the soul even in conditions of material comfort (Frankl, 1959).

This is why Ecclesiastes is not a book of despair but of diagnosis. It clears the ground for a different kind of answer. Purpose cannot be constructed from within a closed system of finite things. It must come from beyond. And that is precisely where the biblical narrative goes.

 

Jesus Defines the Shape of Human Flourishing

When a lawyer asked Jesus to identify the greatest commandment, the answer Jesus gave was not primarily about individual moral performance. ‘You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself‘ (Matthew 22:37-39, ESV). In a single stroke, Jesus reorients the entire teleological question. The purpose of human existence is relational—vertically toward God and horizontally toward neighbor.

This matters enormously for Christian witness. Contemporary Western culture tends to locate human purpose in individual achievement, personal brand development, or what sociologist Robert Bellah called ‘expressive individualism’—the notion that the authentic self is a project to be constructed and displayed (Bellah et al., 1985). Against this, Jesus insists that you are not the center of your own story. You are a relational creature designed for love—a love that has its source and sustaining energy in the character of God himself. Purpose defined by love is inherently other-directed, which means it cannot be found in isolation. It must be embodied in community and mission.

When you sit across from a colleague who is burning out chasing a promotion, or a young adult who feels unmoored after achieving everything they were told would make them happy, you are sitting with someone in a teleological crisis. The question ‘What is the purpose of human existence?’ is being answered experientially by the gaps in their life. The Great Commandment offers not an argument to win, but an invitation to explore—a question you might ask: ‘When do you feel most genuinely alive—most like yourself? What does that tell you about what you were made for?’

 

The Great Commission as Cosmic Invitation

In Matthew 28:18-20, the risen Christ delivers what has become known as the Great Commission: ‘All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you‘ (ESV). These words are usually read as a mandate for church programs or missionary organizations. But read through the lens of teleology, they are something more personal and more profound: they are an invitation for every individual follower of Jesus to find their purpose by participating in God’s redemptive mission in the world.

This is not merely an assignment. It is an answer. The question ‘What is the purpose of my life?’ receives here a cosmic-scale response: you are invited to participate in the restoration of all things under the lordship of Jesus Christ. Your vocation, your neighborhood, your relationships, your conversations—none of them are accidental. They are the specific territory of your participation in the missio Dei, the mission of God.

Missiologist David Bosch described the missio Dei as God’s redemptive movement toward the world, in which the church is privileged to participate (Bosch, 1991). But Bosch was careful to note that this participation is not institutional alone—it is personal. Every believer is commissioned. The tentmaking tradition, from Paul’s leather craft in Corinth to contemporary Christians integrating vocational work with missional presence, demonstrates that there is no secular-sacred divide in God’s purpose. The professor who asks excellent questions in a seminar room, the nurse who prays in the hospital corridor, the entrepreneur who builds a business with kingdom values—all of these are expressions of individual purpose nested within God’s cosmic restoration project.

 

Colossians and the Christological Frame of All Meaning

Paul’s letter to the Colossians contains one of the most sweeping christological statements in the New Testament. In describing Jesus, Paul writes: ‘He is the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible… all things were created through him and for him. And he is before all things, and in him all things hold together‘ (Colossians 1:15-17, ESV).

The phrase ‘for him’ is the teleological center of the universe. All things—including you—were created not merely by Christ but for Christ. Purpose is not a human construction. It is not a social consensus. It is not an emergent property of evolutionary processes. It is inscribed into the fabric of reality by the One in whom all things cohere. This means that when someone experiences the collapse of their own attempts to generate meaning—when hedonism leaves them empty, when careerism leaves them hollow, when consumerism fails to satisfy—they are not experiencing a psychological malfunction. They are experiencing the grain of the universe.

C.S. Lewis captured this intuition memorably in Mere Christianity when he observed that if the whole universe has no meaning, we should never have found out that it has no meaning—just as we could not feel wet without knowing what dry was (Lewis, 1952). The fact that human beings universally experience the hunger for meaning, the ache of purposelessness, and the joy of transcendent significance points not to a quirk of neurochemistry but to a design feature. We were made for something—and that something is Someone.

 

Secular Substitutes and the Art of Asking Good Questions

One of the most important skills in conversational witness is what might be called the ability to hear the teleological hunger in a person’s story. People who have rejected—or never encountered—the biblical narrative of purpose are not living in a vacuum. They have filled the space with substitute meanings. Recognizing these substitutes, and asking questions that surface their inadequacy with gentleness and genuine curiosity, is at the heart of dialogical witness.

The philosopher Albert Camus argued that the most fundamental philosophical question is why one should not commit suicide—that is, whether life is worth living in the absence of transcendent meaning (Camus, 1942). His answer was defiant affirmation of life in the face of absurdity. But this is a desperate solution. It requires heroic self-deception: to live as though life matters while believing that it does not. Honest atheism, as philosopher Thomas Nagel has acknowledged, faces a profound difficulty in accounting for why human meaning-making should be trusted or taken seriously in a universe that produced consciousness by blind accident (Nagel, 2012).

Here are some of the common teleological substitutes you will encounter in conversation, along with questions that invite reflection:

• Careerism: Identity entirely in vocational achievement. Question: ‘When you imagine reaching the top, what do you think you’ll feel? What happens if you get there and it’s not enough?’
• Hedonism: Pleasure as ultimate purpose. Question: ‘What’s the most alive you’ve ever felt? Was it a moment of pleasure, or something else?’
• Nationalism or tribalism: Ultimate meaning in collective political or ethnic identity. Question: ‘What would it mean for your purpose if your nation ceased to exist—or if it succeeded but did so unjustly?’
• Consumerism: Fulfillment through material acquisition. Question: ‘When have you bought something you were convinced would make you happy, and how long did the satisfaction last?’
• Self-actualization: Personal potential as the highest good. Question: ‘When you’ve grown the most as a person—what was it in service of? Was it just about you?’

These are not gotcha questions. They are genuine invitations to reflection, asked from a posture of curiosity and care. The goal is not to expose people as intellectually inconsistent, but to walk alongside them as they discover that their own experience testifies to the inadequacy of purpose without God.

 

Dialogical Witness as Participation in God’s Mission

The conversational approach to Christian witness is not a technique. It is an expression of the relational nature of the gospel itself. The God who is Trinity—Father, Son, and Spirit in eternal communion—created human beings for relationship, redeems us through the incarnational entry of the Son into our world, and sends us as witnesses precisely because witness is a relational act. You cannot faithfully represent the gospel of the God who is love through a non-relational methodology.

This means that dialogical witness begins not with your presentation but with your attention. Before you share anything, you listen. You ask. You honor the dignity of the person before you by taking their story seriously. You resist the temptation to reach for your argument before you have truly heard their question. As Paul modeled in Athens—observing the city, reading its inscriptions, engaging its philosophers on their own terms before presenting the resurrection (Acts 17:16-34)—faithful witness is culturally attentive and personally engaged.

The Missio Dei Circumplex framework developed at Missional University gives us a rich vocabulary for this engagement. God is active in the lives of people before we arrive in the conversation. He is calling, gifting, positioning, and preparing hearts. The role of the individual witness is not to generate meaning for someone else but to help them see the meaning that has been written into their existence by the Creator—and to point toward the One in whom that meaning finds its fulfillment.

 

Already and Not Yet: Holding the Tension in Witness

One of the most important theological frameworks for conversational witness around purpose is the ‘already/not yet’ tension of kingdom theology. The kingdom of God has broken into history in the person and work of Jesus Christ—already. The full restoration of all things under his lordship is not yet complete. We live between the first and second advents, which means that Christian witness must hold together honest acknowledgment of the brokenness of the present world with confident proclamation of the coming wholeness.

This matters for teleological conversations because many people’s objections to the Christian account of purpose are rooted in the gap between what the gospel promises and what they observe in the world. ‘If God has a purpose for human beings, why is there so much meaningless suffering?’ is not a question to be deflected. It is a question to be honored—because it is the right question. The ‘already/not yet’ framework allows you to say, with intellectual integrity: ‘You’re right that the world is not as it should be. That is exactly what the Bible says. The promise is not that everything is fine now, but that the One who made us for a purpose is also the One who is restoring that purpose—and invites us into the restoration.’

The final vision of Revelation 21—God dwelling with his people, making all things new—is not escapism. It is the ultimate teleological statement: creation’s purpose is communion with the Creator, and that communion, fractured by sin, is being restored at infinite cost and infinite love. Every individual life that turns toward Christ finds itself repositioned within this cosmic narrative. That is not a small thing to offer someone who is drowning in meaninglessness.

 

Practical Steps for Teleological Engagement

If you want to grow in your capacity for conversational witness around purpose and meaning, consider the following practices:

First, develop your own teleological clarity. Be able to articulate clearly—not in jargon, but in honest human language—what you believe the purpose of your life is, and how that belief has been shaped by the biblical narrative. Witness is always an overflow of personal conviction. You cannot give what you do not have.

Second, cultivate the habit of asking deep questions. In your next significant conversation with a non-Christian friend or neighbor, practice the question: ‘What gives you the most sense of meaning or purpose in your life right now?’ Then listen—really listen—before you say anything else. Let the answer shape the direction of the conversation.

Third, read broadly in contemporary culture’s attempts to answer the teleological question. Read Frankl’s Man’s Search for Meaning. Read Camus. Read the popular self-help literature that your neighbors are actually reading. Understand the substitutes from the inside before you critique them. Apologetics that does not understand what it is engaging is not persuasive—it is merely loud.

Fourth, connect your own vocation to the missio Dei. Whatever you do—teaching, parenting, building, healing, creating, leading—ask regularly: How is this work participating in God’s restoration of all things? When your ordinary life is shaped by a missional imagination, your witness becomes organic rather than programmatic.

Fifth, practice the discipline of confession. When you encounter someone whose substitute for meaning has real dignity—whose careerism, for example, has produced genuine good in the world—acknowledge it. The apologetic task is not to tear down everything a person has built. It is to show how the good in their life finds its truest grounding and fullest expression within the framework of God’s purpose, not outside it.

 

Conclusion: The Question Beneath All Questions

The question of purpose is not an abstract philosophical problem. It is the lived experience of every human being you will ever meet. It surfaces in the exhaustion of the overachiever, the quiet despair of the retiree who doesn’t know what comes next, the existential vertigo of the young adult entering a world that offers enormous freedom and very little direction. It is the question beneath all questions.

Christian witness that engages this question—not with packaged answers but with genuine curiosity, deep listening, and the confident good news that the universe was made by and for the One who became flesh and dwelt among us—is both apologetically compelling and profoundly human. It honors the person before you. It trusts the Spirit who has already been at work in their life. And it points, with love and conviction, to the One who is himself the answer: the Christ in whom all things hold together, and through whom all things will be made new.

You are not just sharing information. You are extending an invitation to a person created for a purpose they may not yet know—to step into the story that was written for them before the foundation of the world.
