Genesis 6:22

Thus Noah did; according to all that God commanded him, so he did. (Genesis 6:22 NKJV)

Noah did what God said. He didn't know what rain was, but he trusted God. His faith wasn't just that God exists, or a philosophical belief, but his faith motivated him for action, and that saved him. What kind of faith do you have? Does it motivate you to action? What kind of action?
