A good argument for the Bible?

Actually, it is a good moral guide (love others as you love thyself, do not be angry with your brother or call him names, turn the other cheek, etc), morality is subjective outside of Christianity, which is why devout Christians are usually more moral than the godless heathen who choose to go after their own lusts and after their own confusions with their border line humanist ideologies that are clearly expressed in their hedonism.
