[ecko_quote source="Ephesians 4:26"]Be angry, and do not sin” do not let the sun go down on your wrath[/ecko_quote]
Few things are more destructive to Christians who anger. Anger causes us to lose our self-control and to say and do things we would otherwise never consider saying or doing. Anger, if allowed to remain, turns into bitterness that eats away at our hearts. Scripture consistently commands believers to put away anger and lists it as one of the sins of the flesh (Eph 4:31).
At times, we try to defend our anger by citing Ephesians 4:26. As additional proof, we argue that Jesus cleansed the temple in “righteous indignation”. Ephesians refers to anger that does not lead to sin. Jesus was capable of being angry without sinning. When Jesus cleared the temple, Scripture does not indicate that He was angry (Matt 21:12; Mark 11:15-18; Luke 19:45-46)
We must be careful not to justify our anger with Scripture. Ephesians 4:31 commands us to put away all anger. That does not mean that we cease to have strong convictions or lose our desire for justice. It does mean we refuse to allow others’ sins that cause us to sin. Anger does not bring about God’s redemptive work; far more often it hinders what God is working to accomplish.
If you feel that you have a righteous anger because of something that has happened, see if you are holding anger in your heart without sin. Is your anger turned into bitterness? Is it causing you to make an excuse for your ungodly behavior? You must examine any anger within you and allow God to remove any sinful attitude that your anger may have produced.
Even the best-motivated anger can sour, and we are therefore to put it aside at the end of the day. Taken to bed, it is likely to give the devil an opportunity to use it for his purpose. If anger is prolonged, one may begin to seek vengeance and thereby violate the principle taught in Romans 12:17–21.
Never pay back evil for evil to anyone. Respect what is right in the sight of all men. If possible, so far as it depends on you, be at peace with all men. Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, “Vengeance is Mine, I will repay,” says the Lord. “But if your enemy is hungry, feed him, and if he is thirsty, give him a drink; for in so doing you will heap burning coals upon his head. Do not be overcome by evil, but overcome evil with good.”
