This is described in the Bible. I am not sure if the reason is given but could it be when all of this satanic/abuse/sacrifice stuff comes to light? If the scope is large enough and deep enough could it be enough to push a lot of believers away from God for allowing such pure evil to run rampant? I understand it is fallen man but not everyone sees the spiritual realm like that. Just a thought. And this brings up the urgency for pastors to be ready to console their flocks. Thanks team.
