Millions of people are wasting their lives pursuing dreams of happiness that don't rise above a good marriage, nice kids, a successful career, a nice car, fun vacations, nice friends, a fun retirement, a painless death, and (hopefully) no hell. John Piper calls this a tragedy in the making. He argues that we were created for joy. We were designed to have one life-encompassing passion. In this book he describes his own journey in discovering this great, single passion. And He pleads that at all costs we pursue our joy in the crucified Christ, who is the glory of God. The cost is great. But the joy is worth any cost. Don't buy seductive, tragic promises of worldly joy. Don't waste your life.
