A friend put me on to this amazing website: desiringgod.org - and specifically, a very challenging sermon entitled “Don’t Waste Your Life“, which John Piper delivered to a group of university students in 2003, just after the Bam earthquake killed thousands in Iran.

The “un-wasted life”, according to Piper, is “a life that puts the infinite value of Christ on display for the world to see”.

This message is delivered with passion and with brutal honesty from a man who has spent his life trying to make it count for Christ. I encourage you to listen to the audio version and share it. There’s also a transcript available.
