Discipleship is not merely a matter of thinking rightly; it is about loving rightly. Augustine said it plainly: sin is disordered love, and salvation is the reordering of our loves toward God. The psalmist prayed, “Whom have I in heaven but you? And there is nothing on earth I desire besides you” (Ps 73:25). True discipleship awakens the affections, cultivating a deep desire for holiness, beauty, and the presence of God.

Christianity in the West is living through a decisive moment. The cultural structures that once held faith in place—social norms, educational institutions, even assumptions in law and politics—have eroded. In the past, churchgoing was common, biblical literacy widespread, and Christian moral frameworks generally assumed. Today, that world feels like a distant memory. Faith is often perceived as irrelevant, outdated, or even harmful. Younger generations, shaped by the digital revolution and global pluralism, find themselves presented with a dizzying array of competing worldviews. For many, Christianity is not rejected—it is simply ignored.

In such a world, the call to discipleship has never been more urgent—or more misunderstood. Discipleship is not an event, a class, or a program. It is not a twelve-week curriculum or a checklist of spiritual habits. Discipleship is a lifelong journey of being shaped into the image of Christ. It is the call to leave behind an old way of life and embrace a new identity in Christ, allowing every part of our being—our thoughts, desires, and relationships—to be transformed by his grace.

When Jesus invited his followers with the simple yet profound words, “Follow me,” he was not offering an optional path for the spiritually inclined. He was summoning men and women into the very heart of God’s mission, a life defined by faith, obedience, and transformation. At the core of this journey is the call to love the Lord our God with all our heart, soul, mind, and strength. True discipleship does not simply equip believers with knowledge, nor does it merely demand outward conformity to Christian ethics. It seeks to engage the whole person, reshaping how we think, what we love, and how we live in community.

The challenge is clear: in an age marked by skepticism, apathy, and radical individualism, how can discipleship form whole, mature believers? The answer, I believe, lies in recovering a threefold vision of Christian formation—discipleship of the mind, discipleship of the heart (through imagination), and discipleship in community. This holistic vision is not only rooted in Scripture but illuminated by the writings of C. S. Lewis, who saw more clearly than most the cultural and spiritual crises of modernity.

Discipleship of the Mind: Cultivating Intellectual Depth

For many today, faith and reason appear to be enemies. The narrative of secular culture is that belief in God is a leap into irrationality, a surrender of critical thinking, or at best, a private preference. Scientific materialism tells us that the only truths worth believing are those proven in laboratories, while relativism insists that truth itself is fluid and subjective. The so-called New Atheists have hammered away at Christianity as intellectually obsolete.

Caught in this climate, many Christians are unprepared. They know fragments of the Bible, perhaps a few doctrines, but they cannot explain how their faith makes sense of the world. And when challenged by skepticism—whether in a university classroom, workplace conversation, or even at the dinner table—they struggle to respond.

But the Christian faith has never asked believers to abandon reason. From the wisdom tradition of Proverbs—“Get wisdom, though it cost all you have” (Prov 4:7)—to Paul’s exhortation to “take every thought captive to obey Christ” (2 Cor 10:5), Scripture calls us to love God with our minds. Jesus himself commanded, “Love the Lord your God…with all your mind” (Mark 12:30). A faith that does not think will soon collapse.

Church history bears witness to this truth. Augustine wrestled with philosophy before bending his knee to Christ. Aquinas crafted a grand synthesis of theology and reason. Pascal spoke of the “reasons of the heart” that reason itself must acknowledge. And in the twentieth century, C. S. Lewis offered a model of intellectual discipleship that continues to shape countless lives.

Lewis, once an atheist himself, came to faith not by suppressing reason but by following it. His apologetic writings—Mere Christianity, Miracles, The Problem of Pain—demonstrate that Christianity not only withstands rational scrutiny but provides the most compelling framework for truth, morality, and meaning. “I believe in Christianity,” Lewis wrote, “as I believe that the sun has risen, not only because I see it, but because by it I see everything else.” That is discipleship of the mind: to see reality through the lens of Christ, to think God’s thoughts after him.

What would it look like for the church to recover this intellectual depth? It would mean creating communities where hard questions are welcomed rather than silenced. It would mean integrating apologetics and worldview training into discipleship, not as optional electives but as essential formation.
