John Piper preached "Boasting Only in the Cross" for the 2000 Passion One Day in Memphis, TN to thousands of young adults. The sermon became the catalyst to the book and Lecrae's rap song, "Don't Waste Your Life:"
Don't waste your life. It is so short and so precious. I grew up in a home where my father spent himself as an evangelist to bring the gospel of Jesus Christ to the lost. He had one consuming vision: Preach the gospel. There was a plaque in our kitchen for all my growing up years. Now it hangs in our living room. I have looked at it almost daily for about 48 years. It says, "Only one life, twill soon be past. Only what's done for Christ will last."
