Morals are determined by God, not by people.

This is the same God that drowned the entire world, allowed his most devout follower to be tortured by Satan as part of a wager (and his family to be destroyed), glories in the tearing apart of little children, and allowed his supposed son to be torture executed in one of the most horribly cruel ways humans have ever devised.

Your God is fickle.

You'll forgive me if I find you description and promise of the perfectness of heaven based on the supposed goodness of God to be somewhat suspect.
