“Belief that you are accepted by God by sheer grace is profoundly humbling. The people who are fanatics, then, are not so because they are too committed to the Gospel, but because they are not committed enough. Think of the people you consider fanatical. They’re overbearing, self-righteous, opinionated, insensitive, and harsh. Why? It’s not because they are too Christian but because they are not Christian enough. They are fanatically zealous and courageous, but they are not fanatically humble, sensitive, loving, empathetic, forgiving, or understanding - as Jesus was. What strikes us as overly fanatical is actually a failure to be fully committed to Jesus and His Gospel.”
