Noah - A Man Called Righteous

God has very good eyesight! Somehow or other everyone knows the line, "... Noah found grace in the eyes of the LORD." That's Genesis 6:8. Only three verses later we read, "Now the earth was corrupt in God's sight, and the earth was filled with violence." Did the wicked know that God saw them? Or did they convince themselves they were getting away with their crimes? For that matter, did Noah realize that his righteousness was visible from Heaven?
