The Rev might have something there. I think of Abraham and the 'test' that God set for him by telling him to slaughter his beloved son in order to prove his faith - only to give him a last minute reprieve.
Think about it. This God knows everything (apparently). Therefore when he set the test, he knew that Abraham, although reluctant, had faith enough to kill his son, and God also knew that he was, at the last minute, going to stop the slaughter. What sort of twisted, evil, mind, that already knows the outcome, would take pleasure in tormenting a human being like that?
I think you have to think very seriously about the sort of character you are giving your allegiance to. Going on this God's track record, he isn't something that anyone in their right mind would worship, or seek to emulate. In fact, in this day and age he would be considered dangerously mentally deranged. He was often incredibly cruel, he was rarely kind, and he is long gone, so he doesn't use you to do kind deeds. You do them because you're a thoughtful and caring person. It's as simple as that.
