Desiring God by John Piper
God is most glorified in us when we are most satisfied in Him—This is the essence of Christian Hedonism, the central theme of John Piper’s Desiring God.
I finally had the chance to read this book and found it radically God-centered and mind-blowing. It invites people to intensify our longing for happiness, which is good and not sinful, and pursue it in God, to whom the deepest and most enduring happiness can only be found. Throughout the book, Piper expounds on Christian Hedonism and how it affects several aspects of Christian living, which include worship, love, money, marriage, missions, and suffering.
I highly recommend this book to you. You may get a soft copy or a PDF download at the Desiring God Web site.
