Hebrews 11:7-8

By faith [with confidence in God and His word] Noah, being warned by God about events not yet seen, in reverence prepared an ark for the salvation of his family. By this [act of obedience] he condemned the world and became an heir of the righteousness which comes by faith. [Gen 6:13-22] By faith Abraham, when he was called [by God], obeyed by going to a place which he was to receive as an inheritance; and he went, not knowing where he was going.
