The real question is: "Can you be good with a bronze age or 6th century God?"
I think good people will be good despite their Gods.
The answer is, since God created all things, He also created the natural goodness that you might have, in you.
Consider the bad guy... the real bad guy... a guy who goes around killing and stealing and raping and doing every other bad thing. As long as he is alive, he will do good now and then. He has a few people who are friends. He might even do the good of giving his life up for his friends when necessary.
Good is something God put in us all when He made nature.
