Most of theist philosophy is to help your fellow man in your community and that thought comes from god .
No. For example, if you read the bible, most of it is about the importance of having one God and making sure it is the right god. There's a little about helping your fellow man, but it's a negligible amount compared to the stuff about being obedient to God and so on.
So if you don't have that command from god , you don't have such obligation , so what does that lives you with ? Self centered
That's only one option among many.
If you're an atheist humanist, for example, then obviously you're not self-centred, because humanism is a philosophy that espouses things like equality, moral duty and so on.
But your idea that people are only moral when God commands them to be is flawed anyway.
Ask yourself the question that Plato asked 2000 years ago: is something right or wrong only because God said so, or is there a standard of morality that is independent of God?
If things are only right and wrong because God said so, then morality is arbitrary. But if God says things are right and wrong because he knows from some other source what is right and wrong, then morality doesn't come from God - it comes from that other source.
