Noah was a righteous man amongst the corrupted in his generations. During the flood, he was kept safe along with the animals in the ark, for he had found favour in God’s eyes. When the flood was over, God made a rainbow appear and promised Noah that He would not destroy the earth again.
When Jesus ascended from the water, the heavens were opened unto Him—lo and behold, a voice from heaven declared that Jesus was the promised Saviour and the Spirit of God descended as a dove, alighting on Christ. “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.” (John 3:16)
