There are four issues you must walk him through: 1) the nature of temptation, 2) the possible responses to this temptation, 3) the motives for those responses, and 4) the sinful response he chose. In this process you stand both above him and beside him. You are above him because God has called you to a role of discipline and correction. You are beside him because you, too, are a sinner who struggles with anger toward others.
