Do You Know the Most Dangerous Person in Your Church? The most dangerous person at your church is the apparently smart guy who is un-teachable. Meaning that he has it all figured out. We learn of some reasons as to why he is dangerous, and what to do about it. He is the classic, “Don’t confuse me with the facts, I know what I believe” guy. This is the guy who seems to have a lot of biblical knowledge. He can drop the 30 lb. words and effectively argue his point. Very often, he is quite involved and appears to have things together. However, he is dangerous because of the reason you would not think; he is un-teachable. A church that is teachable brings its leaders joy. A church or church member who is not, robs them of joy.
