Noah's full name- Noah
Noah was a Farmer/Carpenter; however when God told him to start prophesying to the people, he became a Prophet.
Faithful as he is, he obeyed and followed God's command and he preached for as long as God wanted him to. The earth was filled with sin and building this ark as a means to evacuate while the God is destroying the world is the topic the Noah was preaching about.
There is no biblical evidence about Noah saying anything, but I want to emphasize his preaching.
In the latter days, just right before God will send another "flood", we have to be strong in our faith or on what we really think and believe who God really is. There will be a lot of fanaticism, chaos, anarchy in nations, natural disasters, and a lot more ways the devil uses to try to break the cord between God and us.
