Ephesians 4:26-27

Be angry (at sin-at immorality, at injustice, at ungodly behavior) yet do not sin; do not let your anger (cause you shame, nor allow it to) last until the sun goes down. And do not give the devil an opportunity (to lead you into sin by holding a grudge, or nurturing anger, or harboring resentment, or cultivating bitterness).

Anger is more than an emotion. It is a gateway (if not controlled) to enter into sin. Nothing peaceful ever grows in an angry heart. The seed of peace can’t take root and gets dug up by offense, resentment, and bitterness, producing anger that gives an entryway for the devil. We have a choice to thrive in peace or get stuck in anger. Choose peace.
