John Piper, retired pastor over 30 years to Bethlehem Baptist Church in Minneapolis, MN, wrote a book called Desiring God that became a foundation and website resource, DesiringGod.org. Piper has also been known for his message Boasting Only in the Cross which provided the popular phrase, "Don't Waste Your Life." This also turned into a book and rap song by Lecrae. The DesiringGod.org website contains an incredible amount of content that covers specific Bible passages, topics, question and answers, difficult subjects, conference information, and biographical sermon series of Christian people throughout history. The resounding message Piper makes from pastoring and Desiring God is that "God is most glorified when we are most satisfied in him."
