I think the scriptures speak for themselves. Don’t be angry and if you do, don’t go to bed angry, but forgive.
Ephesians 4:26 Be ye angry, and sin not: let not the sun go down upon your wrath:
If a Holy God can forgive us, we can always forgive others.
Matthew 6:14 For if ye forgive men their trespasses, your heavenly Father will also forgive you:
Matthew 6:15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
The Bible says if you are slow to anger you’re of great understanding.
Proverbs 14:28 He that is slow to wrath is of great understanding: but he that is hasty of spirit exalteth folly.
We are to live peacefully with everyone if it is possible and to overcome evil with good.
Romans 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men.
Romans 12:18 If it be possible, as much as lieth in you, live peaceably with all men.
Ephesians 4:31 Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice:
Proverbs 15:1 A soft answer turneth away wrath: but grievous words stir up anger.
Proverbs 15:8 A wrathful man stirreth up strife: but he that is slow to anger appeaseth strife.
Psalms 37:8 Cease from anger, and forsake wrath: fret not thyself in any wise to do evil.
Romans 12:21 Be not overcome of evil, but overcome evil with good.
1 John 4:7 Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
