Hebrews 11:7-8

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.

11:8 By faith Abraham obeyed when he was called to go out to a place he would later receive as an inheritance, and he went out without understanding where he was going.
