✝️ The Nature of Human Existence and Morality
A Christian Perspective Through the Eyes of Faith Leaders
🌱 Summary
Christian leaders throughout history have consistently held that human existence is not accidental or meaningless but intentionally created by God. Humanity bears the image of God (Genesis 1:26–27), which grants every person inherent dignity, purpose, and a moral compass. At the same time, due to the Fall (Genesis 3), humanity also carries a sin nature, which distorts that image and necessitates redemption through Jesus Christ.
Morality, from a Christian standpoint, is grounded in the character of God, not in human consensus or cultural evolution. God’s moral law is revealed in Scripture, written on the human heart (Romans 2:15), and clarified through the life and teachings of Jesus Christ. Christian ethics are not simply rules to follow, but a way of life that reflects the kingdom of God and honors His holiness. Morality, therefore, is not optional for the Christian but foundational. It shapes how we view justice, truth, compassion, and holiness.
Prominent Christian leaders from Augustine to C.S. Lewis, and from John Calvin to Tim Keller, have offered rich reflections on how human identity and morality are inseparable from our relationship with God. These reflections are rooted in Scripture, informed by tradition, and energized by the ongoing work of the Holy Spirit in the lives of believers today.
🧟 The Nature of Human Existence
1. Created in God’s Image
“So God created man in His own image…” – Genesis 1:27
- Augustine of Hippo: Taught that humans were created with a will and reason, enabling us to seek God. Yet because of sin, the will has been bent inward (concupiscence), needing divine grace to be healed. His Confessions reveal the restless heart of a man who found peace only in God.
- John Calvin: Emphasized the imago Dei but also the total depravity of man due to the Fall. For Calvin, human existence finds its meaning only in knowing God and living in covenant with Him. Calvin’s doctrine was not just intellectual—it was pastoral, driving believers to dependence on divine mercy.
- Pope John Paul II: Reaffirmed that the image of God in humanity underlies our dignity, moral worth, and capacity for relationship. His Theology of the Body further explored how the human body, sexuality, and relationality reflect God’s purpose in creation.
- Tim Keller: Preached that while humans are more sinful than we can imagine, we are also more loved and valued than we dare hope — both realities are rooted in our being God’s image-bearers. This tension creates a humility and boldness that fuels Christian mission.
2. Fallen but Redeemable
- C.S. Lewis in Mere Christianity wrote that we are made for another world; the sense of “ought” within us is a clue to our true origin. He saw human longing for good and beauty as evidence of a fallen yet divine design. Lewis’ argument from desire stands as a powerful apologetic for divine purpose.
- Dietrich Bonhoeffer taught that real human existence is only possible in Christ. Without Him, we are alienated from our true selves and others. His own martyrdom during WWII testifies to the deep cost of living a morally faithful life.
- Billy Graham regularly preached that all people are born with a spiritual void, which only Jesus Christ can fill. His altar calls and gospel invitations were grounded in a belief that God’s love can redeem even the most broken heart.
3. Purpose-Driven Life
- Rick Warren: In The Purpose Driven Life, he reminded millions that “you were made by God and for God,” and until we understand that, life will never make sense. He connected theology to practical living in a way that resonated with everyday Christians.
- Christian leaders agree that our existence isn’t defined by our achievements, politics, or culture, but by our relationship with our Creator and our mission to reflect His glory. This reframes how Christians view vocation, family, and suffering.
⚖️ The Nature of Morality
1. Rooted in God’s Nature
“Be holy, because I am holy.” – 1 Peter 1:16
- R.C. Sproul: Morality is not arbitrary; it flows from God’s unchanging character. Right and wrong are not defined by society but by God’s holy standard. For Sproul, holiness is not just one attribute of God among others but the centerpiece of His moral identity.
- John Stott: Emphasized the Sermon on the Mount as the core of Christian ethics — love, humility, mercy, and purity flowing from a renewed heart. His writings bring theological depth and cultural relevance to ethical living.
- Francis Schaeffer: Warned against the collapse of objective moral standards in secular society. For Schaeffer, abandoning biblical truth leads to relativism and despair. His vision was prophetic, urging the church to speak into the moral crises of our age.
2. The Moral Law Written on the Heart
“They show that the requirements of the law are written on their hearts…” – Romans 2:15
- C.S. Lewis: Observed that across cultures there’s a “Tao” — a shared moral law. In his view, this universal moral intuition points to a Lawgiver. His insights have helped Christians engage skeptics who claim that morality is merely cultural.
- Tim Keller: Often preached that every human being instinctively knows that justice, truth, and love matter, because we were created by a moral God. He linked this to the gospel, showing how the cross satisfies both justice and mercy.
3. Morality as Relationship, Not Just Rules
- Dallas Willard: Taught that morality isn’t about sin-management but about living with God in everyday life, cultivating a character shaped by grace. He urged believers to focus on transformation, not just conformity.
- N.T. Wright: Framed Christian ethics in terms of participation in God’s new creation — living now in a way that reflects the kingdom that is to come. His vision for “the already and the not yet” helps believers navigate the tension between present struggle and future hope.
🔍 Analysis: Common Themes Across Christian Leaders
A. God-Centered Human Worth
Every theologian and pastor surveyed agrees that human beings derive their worth and meaning from being created by God. Modern thinkers like Keller and Warren present this in accessible terms, but they echo ancient truths held by Augustine and Calvin. This consistency through the centuries reveals a core theological conviction: human value is bestowed, not earned.
B. Sin and the Need for Redemption
No Christian doctrine of existence is complete without recognizing humanity’s fallen condition. Leaders across time stress the brokenness of our moral compass without God — and the absolute necessity of Jesus as Redeemer. In Him, the shattered image of God is restored, and moral clarity becomes possible.
C. Objective Morality, Not Cultural
Christian morality is not derived from evolving societal norms. Rather, it’s rooted in God’s nature, revealed through His Word, and fulfilled in Christ. Modern apologists like Lewis and Schaeffer have been especially vocal in pushing back against relativism. Their work is a call for the church to be salt and light amid moral confusion.
D. Moral Living as Spiritual Formation
Instead of viewing morality as a checklist, many leaders (Willard, Bonhoeffer, Wright) see it as a byproduct of transformation — the Spirit forming Christlikeness in us. This highlights that the moral life is not burdensome duty but joyful partnership with God.
🛍️ Real-World Application
- Identity Crisis Solved in Christ
In a culture that often tells people to “find themselves,” Christianity says you already have an identity — as a beloved image-bearer of God. The Christian message offers an anchor in a time of identity confusion. - Moral Clarity in a Confused World
When societal values shift, Christians stand firm on biblical truth, not because of stubbornness, but because they serve a God whose moral character doesn’t change. Moral clarity brings peace and courage when the world seems unsteady. - Purpose Beyond the Self
While the world promotes self-fulfillment, Christian leaders challenge us to live for God’s glory, loving others, and reflecting Christ in every area of life. This countercultural call provides deeper joy than self-centered living ever could. - Grace as the Engine of Morality
Christian morality isn’t about earning favor with God but responding to the grace we’ve received. Leaders remind us that a moral life without grace becomes legalism, but with grace becomes worship.

🙏 Conclusion: Why It Matters
Understanding the nature of human existence and morality isn’t just theology — it’s the foundation for how we live, treat others, and relate to God. Christian leaders from ancient bishops to modern pastors have reminded us that we’re not cosmic accidents, nor are we free to invent morality from scratch.
Instead, we are designed with purpose, accountable to a holy and loving Creator, and invited into a life of moral beauty shaped by His grace. Our existence has meaning. Our choices matter. And in Christ, both are redeemed for eternal good.
“You have made us for Yourself, O Lord, and our hearts are restless until they rest in You.”
— Augustine of Hippo
