Badfish: God made everything. He has every right to do as he pleases with his own creation. Just because you—who were made by God—do not understand your maker, it does not mean he does not exist. From our viewpoint, many things seem unjust. But we don’t know everything. He does. And his ways are higher than ours.
This concept frightens me. We describe god as good, and just, and loving. He not only displays these qualities, he personifies them. God is love. No one can be as good as god. His justice is true justice. And so on.
And then, we turn around and claim that his ways are inscrutable to us, and we do not have the understanding necessary to judge his actions. The things that seem unjust to us, only seem so because we don't comprehend god's ways.
In other words, god can do anything, and it is good. He can take any action, and it is done out of love. He can do things that we would roundly and utterly condemn a human for, and it would be a hallmark of justice. So when god drowns the world to no real benefit, it is the loving and just act of a good person. When he instantly strikes down a man for the simple act of trying to steady the ark of the covenant, it is a just act by a loving deity. When he orders his army to sack a city and cut down all of its inhabitants --save for the virgin girls that they can take as wives-- there is nothing wrong with this.
So words like good, kind, loving, and just mean something very different when we apply them to god. They do not represent the expectations we have of a human being. What action could god take that you would consider evil? Or hateful? Or unjust? None. Nothing this being does can be seen as a bad thing.
You expect to spend an eternity with an unpredictable and unstoppable being whose actions --no matter how horrifying-- must be praised. I certainly hope that no such being exists!
