Hebrews 11:7

Verse 7. By faith Noah. It is less difficult to see that Noah must have been influenced by faith than that Abel and Enoch were. Everything which Noah did, in reference to the threatened deluge, was done in virtue of simple faith or belief of what God said. It was not because he could show from the course of events that things were tending to such a catastrophe; or because such an event had occurred before, rendering it probable that it would be likely to occur again; or because this was the common belief of men, and it was easy to fall into this himself. It was simply because God had informed him of it, and he put unwavering reliance on the truth of the Divine declaration.
