In my reading of the Bible, I haven't really found a whole lot of good morals, and I don't see the point in communicating morals via myths made up by ancient agricultural societies. The Bible is openly racist (Yahweh has a "chosen people" and orders them to indiscriminately kill off "sinful peoples"), sexist (tells wives to submit unquestioningly to their husbands), pro-slavery (try reading Exodus 21, the chapter after the Ten Commandments that Biblical moralists love to trot around), and homophobic (tells us to stone the gays).

We can see, from our modern perspectives, why things like slavery and stoning gays is wrong, which proves that we don't need religion to look for moral advice. We can use basic ideas like equality, sympathy and cooperation to determine how we should act toward others. We should not judge the righteousness of an action by whether or not it is a "sin" which somehow offends a magical sky wizard; we should judge the righteousness of an action by what the consequences of those actions are for others. Morality is constructed by societies of people who want to get along with each other and cooperate to protect each other from threats to their lives and liberties; we can stop pretending that it is imposed on us by some "higher power" who only bothered to tell us about it in some dubious ancient texts that we don't have the originals of.
