If you are angry, don’t sin by nursing your grudge. Don’t let the sun go down with you still angry – get over it quickly; for when you are angry you give a mighty foothold to the devil. [Ephesians 4:26-27 (TLB)]

Sometimes we get angry and, occasionally, that anger is justified. After all, Jesus got angry at the dishonest money changers and merchants and drove them out of the temple. It is right to be angry about injustice and sin. The anger we need to be wary of is selfish anger: the anger that comes from jealousy or when we don’t get our way. We must be cautious about anger when we think we’ve been insulted or undervalued or lose an argument. It’s all right to be irritated or annoyed; being a Christian doesn’t mean we stop having emotions. What it does mean is that we don’t hold on to our anger and let it fester. If it is a righteous anger, we need to do something about it; if not, we need to let it go.
