You just crack me up sometimes, Dr. Tour. As serious as you can be, it's so refreshing to listen to someone of your stature and firm Christian beliefs and hear the sense of humor He gave us. In His image we are made. I once wrote a paper and mentioned that I couldn't figure out why more people didn't speak on God's sense of humor. Think of it - "What if I find 50 righteous men?" Nope, there aren't 50. Then, "What if I find....". Like children, "But mommy, what if I clean my room and brush my teeth without being told to?" He knows our nature. Especially speaking for myself, originally Roman Catholic; I think that's when I learned to bargain with God - as if He needs anything from me to be all that He is. I still err sometimes, and when I catch myself trying to convince God Almighty about my "good idea", I finally smile and give it up, believing that He is probably laughing right now at my human lameness. It becomes, Thy will be done, not mine. He turns out to be right all the time, eh?
