" We are meant to live with God on the throne, with a wide-open heart to him and others. But a contentious, judgmental person has shriveled up inside, shutting down to both God and neighbor. On the outside, a contentious person speaks rotten words that tear down rather than build up and condemn rather than give grace (Ephesians 4: 29). On the inside, a person swept up in sinful anger has become demonic and diabolical—in the truest sense—an image-bearer of the hostile critic of God’s people (James 3: 15; 4: 7). "
