Hebrews 11:6-7

11:6 Now without faith it is impossible to please him, for the one who approaches God must believe that he exists and that he rewards those who seek him. 11:7 By faith Noah, when he was warned about things not yet seen, with reverent regard constructed an ark for the deliverance of his family. Through faith he condemned the world and became an heir of the righteousness that comes by faith.
