Christians, Then Why call him God?

The problem with this inane question, which has been posted here at least 100 times, is that it completely ignores the reality of free will. Is God able to prevent evil? Of course He is! He is omnipotent! All He has to do is revoke the gift of free will, thereby turning humans into mere amoral animals, which cannot commit evil. But He loves us too much to actually do so.
