The descendants of Seth were called the sons of God; the descendants of Cain, the sons of men. As the sons of God mingled with the sons of men, they became corrupt and, by intermarriage with them, lost, through the influence of their wives, their peculiar, holy character, and united with the sons of Cain in their idolatry. Many cast aside the fear of God and trampled upon His commandments. But there were a few that did righteousness, who feared and honored their Creator. Noah and his family were among the righteous few.

The wickedness of man was so great, and increased to such a fearful extent, that God repented that He had made man upon the earth, for He saw that the wickedness of man was great, and that every imagination of the thoughts of his heart was only evil continually.

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.
