I would say the same about all the morality propounded in the Bible. All it really does is reinforce virtues with the promise that they will be rewarded. That doesn't constitute acting as a source of morality. As I say, we already know those things are good. It seems quite obvious that they are (though one might debate some of them - meekness say, following Nietzsche).
How do we know? This has been a source of debate in philosophy for over two thousand years. While I wouldn't wish or, realistically, hope to diminish the complexity of those debates, is it really so hard to recognize a good deed when you see one? Kid drops ice-cream scoop from cone, other kid with two scoops gives one to first, now crying, kid. Better yet, first kid is starving and second kid gives it its dinner.
Do we really need a God to tell us this is a good deed? No and we don't need to be Christians, or Buddhists or adherents of any other belief system, to feel the compassion that drives such an act. The only problems we have with morality are in the realms of the empirical - ethical conflicts and practicability. Other than that, one might debate whether there is anything innately moral in human nature or whether we adopt moral practices in response to the promise of rewards and punishments. Whatever. None of this seems to require the existence of a God and it's not clear how it would be helped by it, except to reassure us that the evil really will be punished, even if they seem to get away with it.
EDIT
Of course, I forgot, the other thing religion does to instill morality is tell us that things we might otherwise deem harmless are immoral - working on the Sabbath, say, or having sex with people of our own gender. Bit of a can of worms really.
