A wise person is a peacemaker

 “Fools give full vent to their rage, but the wise bring calm in the end.” (Prov. 29:11 NIV)

Peacemakers are blessed and called children of God

“Blessed are the peacemakers: for they shall be called the children of God.” (Matt. 5:9 KJV)

Peacemakers are peaceable, gentle, open to reason, full of mercy, good fruits, are impartial and sincere

“But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere.” (James 3:17 ESV)

Peacemakers seek peace

“Turn away from evil and do good; seek peace and pursue it.” (Psalm 34:14 ESV)

Peacemakers restrain words and remain cool

“Whoever restrains his words has knowledge, and he who has a cool spirit is a man of understanding. Even a fool who keeps silent is considered wise; when he closes his lips, he is deemed intelligent.” (Psalms 17:27-28 ESV)
