Just saw this on John Piper's./Desiring God blog, and loved it. He calls it a corrective tract for the prosperity gospel. You go, JP.

If anyone would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake and the gospel's will save it. For what does it profit a man to gain the whole world and forfeit his soul?(Mark 8:34-36)
