Problems with morals depending on religion or god.?

How about the obvious moral short comings of the Bible? The Old Testament especially the Book of Deuteronomy and the Book of Leviticus are especially vicious and call for death for what would be seen as minor trespasses these days. In fact, a long running moral failure joke with the Bible is that it got Slavery wrong (Leviticus 25:44-46 NLT).

How about the question of gods morality? If god knows everything past, present and future then he knows what will happen before it happens and in turn lets immoral things happen. If god knows and has always known what you will do in the future before you were even born, then the future is already written. Why would god create these morals then intentionally create something that defies those morals, then later punish them for doing so?

I'm not quite sure if that was the answer you were looking for but I'm intrigued by philosophy of religion and am not attacking anyones beliefs. Good luck with your philosophy paper.

Here's the most convincing argument:

Religious morals can only be attained through divine revelation. Several people have claimed to witness such divine revelations, but most of them contradict each other. There is no rational method of discerning which of these people are lying and which are telling the truth. If god wanted people to abide by his morals, god would have made them perfectly clear.

Bonus advice:

That's what will help you with your paper, but considering Pascal's wager, I have come to think that it is more rational to pick your favorite religion and follow it's morals than to remain agnostic.
