When we first get saved the Bible tells us to “Be angry, and sin not: let not the sun go down upon your wrath: neither give place to the devil”. Ephesians 4:26-27.
I know Saints that not only allow the sun go down on their wrath/anger, but the moon, the stars, weeks, months and years. As we mature in our Lord Jesus, we should be in Psalms where the writer tells us to “Cease from anger, and forsake wrath (Ps. 37:8). Wrath and anger gives your problems and situations rule over you. Anger makes you small. Don’t be small cease from anger!
