If our creator is love (as my God is) and he granted that ability to his creation, then we can reflect the emotion of our creator. I think emotion is how we can come to know our creator.
Tammy - if the God of the bible was like you, the world would be a better place. I know this is a back handed compliment because you believe God to be all love, so you give credit for your loving disposition to him. This is what selfless people do. You always see the good in people and project your love on to them. I don't thank God for that - I thank you.
If God is the creator, then he is responsible for all emotion, both positive and negative. If not he would be only half of the equation and depend on a partnership with a devil to balance the universe. What you believe works for you, and allows you to make sense of who you are. I have nothing better to suggest replacing it with.
