Whenever sin is accepted in our world, it gives a way for demons to be bolder and more powerful. We are ordered to take our thoughts captive, to center them on Christ and given the fruits of the spirit of Christ, what to center them on. Notice that what let the demons come to the room of Piratzz was letting a movie that showed sin come into his mind. Even our governments are legislating about sinful things. Movies, books, TV, the news opens up thoughts of sin in our world. Demons are given power through our going to listen to these things and accept them in our minds. It isn't only denying the sin, it is disciplining our minds not to let it in in the first place.
The history of people accepting God in our world has been one of extremes. God is a God of truth, and truth is never extreme. Christ arrived at a time when the extreme was in works to save us. Now our extreme is in teaching all about works are obsolete, it is faith that saves us. The extreme of works was wrong, and the extreme of faith is wrong. So demons are strong in our world today through our denial of the power of following faith with works.. It isn't the world who is the greatest enemy of the ways of the Lord, it is the extremes of people who say they follow the Lord. The Pharisees were like our extreme Christian leaders of today.
As an example, today there is a great outcry against any ritual God gave the Jews. Let's examine the food laws. The Jews went to extremes and said that the way to Christ was in what you ate. So scripture said no, no, no, it wasn't what you ate. Scripture taught that it was keeping apart from all sin, and to keep to clean thoughts and this was a daily reminder to do that. So man taught that it was denying Christ to have this reminder. God's teaching, in all this is tossed out and so we go to the movies like Piratzz went to and demons are let close enough to attack us. We may accept scripture reading, prayer, and putting on Christ to remind us of biblical truth, but if we use anything else, says our church, we are denying Christ and of course, if we deny Christ we go to hell. Because of what we eat!!! So a young mother, for instance, overwhelmed with her work and constant need to be on duty, must stop what she is doing to study and pray, to use any other reminders sends her to hell. The Pharisees made almost as much sense with all their nonsense rules and regulations.
