Hebrews 11:6-7

6 and apart from faith it is impossible to please [Him], for it is required of him who is coming to God to believe that He exists and [that] He becomes a rewarder to those seeking Him. 7 By faith Noah, having been divinely warned concerning the things not yet seen, having feared, prepared an ark to the salvation of his house, through which he condemned the world, and he became heir of the righteousness according to faith.
