Not as the world gives, I give unto you. Let not your heart be troubled, neither let it be afraid. That is a false promise of some spiritual leaders of all faiths, including some Christians. Jesus teaches us that if you follow Him and believe in Him, you will have peace in your good times and your bad times. I have written a book on the subject of stress.

A medical diagnosis is suddenly very serious and life threatening. They were bright and were chemistry majors. They partied too hard and had to stay over, they didn't wake up to get to their Monday morning classes on time for an exam. I'll give you a chance for a special exam. I'll give it just to the four of you this afternoon.
