You can't be serious.
Oh gee, I don't know maybe it would be because God supposedly had the power to stop all those horrible events if he chose to do so.
So imagine that your entire family was burned to death in a furnace, while you were starved to death and made to do hard, physical labor all day, being viewed by your captors as something less than human, Oh, and you have this God, this God is all powerful, so if he was disgusted with the Nazis and how they exterminated millions of innocent people, then he should have stopped it.
So basically, they have this all knowing, all powerful God just kinda sitting there and watching while these grave injustices were committed against so many innocent people.
I would lose my faith as well.
What a horrible God to just sit back and watch something like that happen.
I would want no association with any God that would allow such terrible things.
Neither would you, I am sure.
I would really like to know what you think YOU would do in such a situation. Actually, you are really ignorant, so you probably think that you would just pray and love this God that destroyed your family, your people.
