I think its interesting that God felt it important enough (in the few details given about the flood) to tell Moses that “The waters rose and covered the mountains to a depth of more than fifteen cubits.” (7:19)
I don’t think Noah would have been outside, dropping the line to measure the depth because “the Lord shut him in” (7:16) So, this information was known by God and he wanted us to know.
That one sentence causes me to pause on the theory of the flood being limited to one area of the globe. Think about it, water seeks to level itself. If the water was 23 feet “above the mountains” it would pour over those mountains into other areas and continue to rise until it was level. God said it was level at death of more than 23 ft. Some interpreters who want to believe in a local flood would like to translate that as, that quantity of water “washing over the mountains”.
Well, the debate can continue, but the end result is the same; destruction of life was complete. “Every living thing that had breath of life in it’s nostrils died.” (7:22)
God is holy and just. He hates evil and loves righteousness (Psalm 11). Like Noah, we don’t need to fear punishment, but we should definitely respect (fear) His justice.
Noah is a great example for us. I like what the Hebrew writer says about Noah. “By faith Noah, when warned about things not yet seen, in holy fear built an ark to save his family. By his faith he condemned the world and became heir of the righteousness that is in keeping with faith.” (11:7)
God wants faith to lead to action. Noah had that type of faith. That’s the type of faith I want!! Faith that leads to action, that leads to saving my family!!
