Hebrews 11:6-8

And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him. By faith Noah, being warned by God concerning events as yet unseen, in reverent fear constructed an ark for the saving of his household. By this he condemned the world and became an heir of the righteousness that comes by faith. By faith Abraham obeyed when he was called to go out to a place that he was to receive as an inheritance. And he went out, not knowing where he was going.
