Here's one that I especially like.
DEAR REV. GRAHAM: How do you know if it's the devil who is tempting you to do something, or if God is just testing you to see if you'll do what's right? I try to make the right choices, but I'm not sure I always know what to do. --J.T.H.And here's the "important" part of Reverend Graham's answer.
Dear J.T.H.: The most important thing for you to remember is that God never tempts us to do anything wrong.
Yet according to the Bible, God tempted Abraham to kill his son.
God did tempt Abraham, and said unto him ... Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering. Genesis 22:1-2
Which means, I guess, that Billy Graham thinks it isn't wrong for a father to kill his son and offer him as a burnt offering to God. (God would never tempt anyone to do anything wrong.)
