  He is 27 and has the mental maturity of a 12 year old. His favorite programs are watched on the children's channel. He gets very disturbed if there is a mature program that shows violence. His disorder is so bad that if he was not on medication his own brain would destroy him.  He would hallucinate and be driven crazy.
  But Ive had a lot of experience with his different mental disorders that show themselves in his outward behavior. Ive become so good at discerning these behaviors that I can see them coming out of a person who is dealing with one of these disorders. Ive struggle with some leaders about how to deal with these disorders. Ive had situations where I would much rather watch the movie Saw then be subject to this kind of preaching. lol When I think a person needs to be on meds usually its because I have the same kind of relationship with them in a lesser degree as Ive experienced with my son.
  Most of my problems with people who teach the doctrines of grace is that I usually am dealing with someone who knows a system of theology ...i mean parts and bits of a system and they miss apply the word because there is this awful teaching that permeates the American religious system.. Two line theology has been the scourge of our society. Because it places these doctrines under the authority of a man as he applies sanctification. As a person who has grown up in this culture I see how we can take something that is taught and miss apply it in the church. Ive experienced more normal relationships...normal services...in the home school graduation than Ive experienced in the average church.   Ive experience more growth in the theater than in some of the churches ive been in over my life. Not gonna name any so you will not know..ive been to a lot of churches. But all of this can be warped into a disturbing form of torture.
