I hear you, but this supposition is not actually mentioned in The Bible. It seems the Grace of God was on Noah alone, and the Grace of God empowered Noah alone to believe God and obey.
“Thus Noah did; according to all that God commanded him, so he did. Genesis” (6:22)
The Bible does tell us:
“The earth also was corrupt before God, and the earth was filled with violence. So God looked upon the earth, and indeed it was corrupt; for all flesh had corrupted their way on the earth”. (Genesis 6:11-12)
Also:
I know what you mean @Who-me, The Holy Spirit of God was surely involved. Not to put too fine a point on it, but The Bible clearly stipulates that the fullness of “indwelling of The Holy Spirit" was not initiated until after Jesus had arisen, after the once-for-all price for the sins of man was paid-in-full. God would not dwell in the temple (human men) until that temple of God was fully cleansed by the blood of The Messiah. Not until that had been accomplished could God take up residence there.
I concur that Noah had a personal relationship with God, a relationship that was initiated by God Himself. We are told that Noah was a man of Faith, and we also know that Noah looked forward to the future sacrifice of The Christ for his own personal salvation. We know this because Noah depcited the efficatious sacrifice of “The Anonted One” when Noah finally emerged out of the floating box he had been in for a year.
Having been released from the box, and all the animals set-free into the wild, we then read Noah celebrated the salvation of God with sacrifice (a symbolic depiction of the True sacrifice of The Lamb of God). God, having observed the sacrifice made a promise “within His heart”.
Then Noah built an altar to the LORD, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar. And the LORD smelled a soothing aroma. Then the LORD said in His heart, "I will never again curse the ground for man’s sake, although the imagination of man’s heart is evil from his youth; nor will I again destroy every living thing as I have done. “While the earth remains, Seedtime and harvest, Cold and heat, Winter and summer, And day and night Shall not cease.” (Genesis 8:20-22)
I’m not arguing, I’m just trying to straighten what was bent a litte.
