In my experience Christians don't understand the Bible. They want to take everything literally so as to not offend their God even though often the text is ridiculous. For example it is impossible for Jonah to have survived 3 days in the belly of a great fish. The Jonah story is not true but was meant to be about repentance and forgiveness. Balaam's donkey didn't speak. The story's lesson is that you are dumber than an ass if you curse Israel. As for lot and his daughters, the offspring were Moabites and the Ammonites, enemies of Israel The object of this story was to say the Moabites and Ammonites were bastard descendants of incest.
