The bible, which tells us to stone our mothers, brothers, sisters, spouses, fathers, and friends to death if they tempt us with other gods, is hardly a book for moral code. The bible, which is filled with rape, murder, revenge, temptations, and heresy, is hardly a book designed for teaching morality. The bible, which teaches of a god who kills others mercilessly for looking back at a town or touching a "sacred" box, is hardly a good moral teacher. The bible, which teaches a jealous, vengeful, and angry god is hardly one of good morale.
Yes, the bible should be discounted entirely for its lack of scientific evidence and horrible stories about inflicting a man with disease and killing his family and other atrocities. Don't compare the bible with other literature and philosophy. Whereas Homer, Shakespeare, Nietzsche, and others wrote well and taught us lessons, the bible is horrifically written with grammatical errors and historical inaccuracies. Not to mention the story jumps all over the place, is inconsistent even with itself, and holds little to no verifiable evidence. That's expected when hundreds of men wrote and revised the book over the course of thousands of years.
I've actually read the bible and you'd be thinking the same if you did, too. As far as the other books, the Koran and others do not teach morality and peaceful harmony. They teach the killing of infidels in order to attain entrance to paradise, and should one die in the course of doing so, they will get to choose friends and family to go along with them. The Koran specifically teaches no tolerance of followers of other faiths.To the original poster of this thread:
We can at least rule out God's omnipotence from the biblical text (can't say the same for gods of other religions) because the bible says so itself. It looks like even with the help of God, or perhaps God himself, iron is still a little too much:
Judges 1:19 "And the LORD was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron."
