I highly encourage you to read it.
I was profoundly amazed at the kind of life his father had lived just by reading this one line:
(Context: Right after his father's death, John Piper is talking to a random young man sitting outside of his father's hospital room).
"Hello, my father just died. One of the greatest tributes I could pay to him is to ask you, Are you ready to meet God?"
Wow - I know nothing else about Bill Piper (Piper's dad), but I can tell you that if that's what would pay him greatest tribute, this was a man who loved the Lord and spent his life spreading, preaching, and living the gospel.
When I die, I want to have lived in such a way that John Piper describes of his dad. That the most honorable thing for someone to do after my death to pay tribute to me is to share the gospel. Amazing - a life that spurs people to Christ and even afterward in honor spurs others to share the glory of Christ.
