It's funny, considering that God is all powerful that pitiful humans beleive they know what he wants better than him.
For instance, if God actually despised abortion, he could stop it. But babies have been getting killed for ages - if it were actually out of the womb, and somebody had hit it with a car, or it had drowned, people would say something like "God had other plans for her/him" but if it's in the womb, it's the work of the devil, and it's just murder - there's no "greater purpose" or "other plan" from God (supposedly).
If God hated sexual immorality, or homosexuality, he could get rid of it, after all he supposedly destroyed whole cities before because of it. So if it's wrong in his eyes, he should feel free to destroy some more cities right?
Maybe his values have changed, maybe he's just stopped caring, perhaps he has more important projects to work on, or perhaps it's just God's will that people will try their darndest to enforce what they believe is God's will, and thus there is no purpose for him to do his own dirty work.
If we were to leave everything up to God and faith in him, why do we have government? Why do we have police or guns and weapons? What is wrong with letting God have his way? What is so wrong with God's will that even the people who believe in it most, must say that the world he has created is so full of evil?
Why is it that people believe that it's wrong for a women to alter "God's design" by getting breast implants, but it's perfectly all right for them to have their son's genitals mutilated as a child? After all if God had wanted circumcision in his design of man, we'd have been born that way right?
What is it that God's believers just don't get? Why must they make up God's mind for him?
