Hebrews 11:6-7

6 Without faith it is impossible to be well pleasing to him, for he who comes to God must believe that he exists, and that he is a rewarder of those who seek him.  7 By faith, Noah, being warned about things not yet seen, moved with godly fear, prepared an ark for the saving of his house, through which he condemned the world, and became heir of the righteousness which is according to faith.
