The important events that Moses records for us in Genesis are events that we all live with the ramifications. Obviously, creation but also the fall and the flood are events in history that impact our daily lives. The historical account of the tower of Babel is another one of those events that we still feel the consequences today.
At the end of Genesis chapter nine, we find that though Noah was a man that walked with God he was a man. He was blameless in his generation but not perfect. As JC Ryle said, “The best of men are men at best.”
