C.S. Lewis explains that humans are created by God, much like a machine is designed for a specific purpose. Just as a car needs petrol to function correctly, our spirits are meant to be nourished by God Himself. He is the essential element that fuels our existence and happiness. Without this divine connection, achieving true joy and peace becomes impossible.

Lewis emphasizes that seeking happiness outside of a relationship with God is futile, as no other source can provide the fulfillment we crave. True contentment and inner peace are found only in God, underscoring the importance of connecting with Him rather than pursuing personal desires disconnected from faith.
