In order for this whole Christian thing to work, God must be perfect. God must be all-present, all-knowing, and infallible. If it were proven that God was able to make mistakes, even one, then the whole of Christianity would come crashing down. Questions would start to be asked and people would lose faith. The pastors, whose jobs rely on Christians believing and tithing would be at risk. No way they could let that cat out of the bag.
Unfortunately, the Bible itself reveals God to be just another bumbling guy, just like Thor or Zeus.
