Hebrews 11:4-7

It was faith that made Abel offer to God a better sacrifice than Cain's. Through his faith he won God's approval as a righteous man, because God himself approved of his gifts. By means of his faith Abel still speaks, even though he is dead. It was faith that kept Enoch from dying. Instead, he was taken up to God, and nobody could find him, because God had taken him up. The scripture says that before Enoch was taken up, he had pleased God. No one can please God without faith, for whoever comes to God must have faith that God exists and rewards those who seek him. It was faith that made Noah hear God's warnings about things in the future that he could not see. He obeyed God and built a boat in which he and his family were saved. As a result, the world was condemned, and Noah received from God the righteousness that comes by faith.
