Believing in God may have given our ancestors comfort in a hostile world, but the comfort came with a cost.
How many crimes against humanity have been carried out in the name of God? Dare I mention the inquisitions, the crusades, or the twin towers in New York. Nothing so quiets the conscience like believing that God requires you to do it.
Faith in God is also a reason many shirk their responsibility for caring for the environment. It is just going to be burned up in fire by God in the last days anyway.
And isn’t the divide between God’s people and the devil’s people the perfect excuse for war? “He who is not with Me is against Me.” This will never lead to peace on earth.
And finally, believing in God is the cause of much mental distress. There is no inner peace if you are constantly worrying that you might have offended God and hence are headed to hell. We must be cured of the God addiction before we can have real peace of mind.
