We have demon controlled preachers and demon doctrines and hypocritical liars and people who don’t want the Truth; and they’ll go to churches that don’t preach it, and not to ones that do. We have apostasy in the Church. That’s where it’s dangerous. They’ve always infiltrated. They’ve always come in. That is the strategy…
