But if there was one sin above another which called for the destruction of the race by the flood, it was the base crime of amalgamation of man and beast which defaced the image of God, and caused confusion everywhere. God purposed to destroy by a flood that powerful, long-lived race that had corrupted their ways before him. He would not suffer them to live out the days of their natural life, which would be hundreds of years. It was only a few generations back when Adam had access to that tree which was to prolong life. After his disobedience he was not suffered to eat of the tree of life and perpetuate a life of sin. In order for man to possess an endless life he must continue to eat of the fruit of the tree of life. Deprived of that tree, his life would gradually wear out.

More than one hundred years before the flood the Lord sent an angel to faithful Noah to make known to him that he would no longer have mercy upon the corrupt race. But he would not have them ignorant of his design. He would instruct Noah and make him a faithful preacher to warn the world of its coming destruction, that the inhabitants of the earth might be left without excuse. Noah was to preach to the people, and also to prepare an ark as God should direct him for the saving of himself and family. He was not only to preach, but his example in building the ark was to convince all that he believed what he preached.
