The story of Abraham in Genesis 21:8-21 is impossible to preach, so why not take it on this week? In it, God is criminally negligent, Abraham guilty of attempted murder, and the notion of predestination affirmed. There are few places in the Bible more open to controversy. There are some great truths, however, that you can teach using it. You can talk about the sacredness of family, marriage, and the grace of God. You can also preach the great lesson of Scott Peck, that life is painful and we can not grow as people until we embrace the emotional difficulties of our current situation.
