I recall seeing, a couple of years ago, a video clip of John Piper talking about and drawing this graph. Whoever posted the link conveniently also posted a link to Robin Williams drawing the exact same graph in The Dead Poet’s Society.
I can no longer find the video clip of John Piper and wonder if it has been taken down.
I would be curious to know if anyone else recalls seeing the John Piper clip since I am beginning to doubt my own sanity on this. 😉
