It seemed as if Satan had won in his efforts to destroy the line of righteousness, but God's purpose was not going to be stopped.

..........It was a small matter for Him to bring an end to the human race in its corrupt condition.

..............................Genesis 6:11-13
"The earth also was corrupt before God, and the earth was filled with violence.
12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.
13 And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth."
