Hebrews 11:7-8

By faith Noah, being warned of God concerning things not seen as yet, moved with godly fear, prepared an ark to the saving of his house; through which he condemned the world, and became heir of the righteousness which is according to faith. By faith Abraham, when he was called, obeyed to go out unto a place which he was to receive for an inheritance; and he went out, not knowing whither he went.
