“Be angry and do not sin; do not let the sun go down on your anger, and give no opportunity to the devil” (Ephesians 4:26-27 ESV).
Anger is a natural human response to conflict; it can be difficult to maintain self-control in the heat of the moment. We are to react in a manner that pleases God. When we respond in a way that does not honor God, it permits the devil an opportunity to exploit our emotions and lure us into sin. For this reason, the Apostle Paul urged us to forgive quickly. If we end our day in anger, we dwell on negative feelings unnecessarily. God's word encourages us to recognize that this verse is not a suggestion but a command.
