“Be angry and do not sin; do not let the sun go down on your anger, and give no opportunity to the devil.”
Paul does not command pretend calm; he admits anger happens. Sin begins when anger takes up residence.
God gives anger a deadline: sundown. A grudge that sleeps over wakes up holding a lease.
Fed anger becomes a doorway. The enemy does not need a wide-open gate; a crack will do.
Marriages, friendships, and churches rarely die of big fights — they die of small wounds left for tomorrow.
Whoever lies down reconciled rises unburdened. Last night's peace is this morning's gift.
Act: if yesterday's irritation survived the night, settle it now — a message, an apology, or a prayer releasing the offense.
