Noah, that just and perfect preacher of righteousness
For some reason, God really liked Noah. He hated everyone else, though. He hated them so much, in fact, that he drowned every last one of them. Everyone except for Noah (and his family), that is.
What was it that God liked about Noah? Well, the bible doesn't say. It only says that he was a just and perfect "preacher of righteousness."
It isn't until after the flood, though, that we find out about his true character. The first thing that Noah does after the ark hits dry land is to kill one of every "clean" animal species, and burn their dead bodies for God. What an example we have here for modern Christians! These animals were the most endangered of all species, yet Noah was willing to kill them so that God could "smell a sweet savour."
After killing the animals for God, Noah plants a vineyard, gets drunk, and lies around naked in his tent. His son, Ham, happens to see his father in this condition. When Noah sobers up and hears "what his young son had done unto him" (what did he do besides look at him?), he curses not Ham, who "saw the nakedness of his father," but Ham's son, Canaan.
So there you have it. If you want to be just, perfect, and righteous, kill lots of endangered species, get drunk, expose yourself to your children, and then curse your grandchildren because their parents saw you naked. I know it sounds a bit strange, but to God it is just, perfect, and righteous behavior.
