Must reading for every Christian. This is a book to do for small groups, bible studies, and devotions. Builds the foundations for "Christian Hedonsism" in the tradition of Edwards, the Puritans, Augustine, the apostles, Jesus, David, etc.
This book is truly a gem! I never thought I would fly through it in less than a week. Not only does Piper systematically define the joys of God, but leaves such sweet taste in your mouth afterward as well! This books is great if you are looking for something solid on the sovereignty of God, Christology, the atonement, and yes.....even election and predestination. Piper is a well known reformed theologian and Pastor, but by NO MEANS presents his case in a stuffed manner. As in all of Piper's books, he passionately expounds the supremacy of God in all things in a style that I can only define as "sweet calvinism". This book radically changed my view of God, for the better, and showed me the my God was too small! Not only would I recommend it, I would encourage you to pick it up as a gift for your friends as well!
The best extra-Biblical treatment of the person of God that I've ever read. Christians can't understand who God is until they understand what brings Him pleasure. This book answers the hard questions about this- "why does God do what He does?" Piper shows us scripturally what God enjoys and what motivates Him. A MUST-READ!
