Noah was the only person on earth who lived a Godly life, and he communicated with God.
Noah did not need a religion, due to his relationship with god.
Noah was pretty much the only person of his time trying to obey the rules of God (besides his family). God trusted Noah (as well as some others in the near and distant future) to do his bidding without complaints.
I believe the evidence points to him dieing in the flood. There is no mention that he walked with God himself, in fact though he was still alive when God first spoke to Noah, God said Noah was the only righteous man on the earth at that time. And being a righteous man, I believe Noah would have petitioned God to spare his father as well, if he too were walking with God. My response to those who say Noah would have asked God to save his father as well, I also don't believe the reason Noah didn't ask God about him was that he had already died. Noah, had brothers and sisters, and he didn't speak to God about them either, and they were still alive at that time, too.
He didn't Jonah ran away from god. god told noah to build the ark.
Christianity acknowledges that Judaism began with Abraham as the first person after Noah to have a personal relationship with God.
Sometimes God would talk to him directly. Noah talked to Him like we do/can.
Noah was chosen because he was the most righteous man on earth.(Genesis 7:1)(Ezekiel 14:14)He 'walked faithfully with God' (Genesis 6:9NIV)He was a "preacher of righteousness"(2 Peter 2:5 NIV)He showed 'godly fear'(respect)and faith(Hebrews 11:7ASB)
noah found grace by god
The religious truth revealed in the story of Noah is: God's forgiveness and love, and humanity's goodness can overcome evil.
The measurements and the door and window details were given to Noah by God.
Noah was a " righteous man". His belief system was strong enough to make him 'blameless among the people of his time'(NIV) as he preached about the coming destruction (2 Peter 2:5). He 'walked with God'(KJV) (Genesis 6:9), 'standing up' for God's laws and principles, and obediently saving his household from the flood waters. (Hebrews 11:7)
In the Bible, God spoke to Noah directly, not through a dream. God communicated His instructions for building the ark and saving Noah's family from the impending flood by speaking to Noah directly.
