Ephesians 4:26 Be angry but do not sin; do not let the sun go down on your anger.
God has made it clear that He doesn’t want us to act in anger. Instead, He wants us to act in righteousness, just as He is righteous. He wants us to follow the example set by our Lord Jesus Christ. No one person who has ever lied has so exemplified temperament. Insulted, spat upon. mocked – and that was all before He was tried and hung on a cross – and yet this Man did not act out in anger. How can this be? How was Jesus able to be angry and not sin? And what’s more; how can we follow this example?
Jesus had inside knowledge. He was in on the Father’s ways. You see, Jesus understood that all acting out of anger accomplishes is more anger. He knew that there was no situation so big that God would not handle it. He also understood the importance of relationships.
It’s just not worth it to act out of anger. It’s not worth hurt relationships and it’s not worth showing a bad example of a Christ follower to those who may have their eyes on us. If we trust God, we can let Him be the administrator of justice. We can believe that He will take care of the situation that caused us anger in the first place.
