Desiring God Meditations of a Christian Hedonist by John Piper – At the heart of “Desiring God” lies the concept of Christian hedonism, a term coined by John Piper himself. Piper argues that true Christianity is not about denying oneself pleasure or happiness but rather pursuing the highest and purest form of joy – joy in God. He suggests that our ultimate purpose as humans is to delight in God and find our greatest satisfaction in Him.
