"But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.
By faith Noah, being divinely warned of things not yet seen, moved with godly fear, prepared an ark for the saving of his household, by which he condemned the world and became heir of the righteousness which is according to faith."
Hebrews 11:6,7
"Thus I establish My covenant with you: Never again shall all flesh be cut off by the waters of the flood; never again shall there be a flood to destroy the earth."
And God said: "This is the sign of the covenant which I make between Me and you, and every living creature that is with you, for perpetual generations:
I set My rainbow in the cloud, and it shall be for the sign of the covenant between Me and the earth.
It shall be, when I bring a cloud over the earth, that the rainbow shall be seen in the cloud;
and I will remember My covenant which is between Me and you and every living creature of all flesh; the waters shall never again become a flood to destroy all flesh.
The rainbow shall be in the cloud, and I will look on it to remember the everlasting covenant between God and every living creature of all flesh that is on the earth."
And God said to Noah, "This is the sign of the covenant which I have established between Me and all flesh that is on the earth."
Genesis 9:11-17
