“HAPPY are the peaceable,” said Jesus Christ in his Sermon on the Mount. (Matt. 5:9) Such peaceable ones work hard to maintain good relations with others. They repay evil with kindness, and avoid quarreling. (Rom. 12:17, 18) In attitude, word and action, they promote peace. Hence, they are indeed “peacemakers,” exerting themselves to help others to enjoy peace with God and with their fellowmen.
Why, then, can it be said that such peacemakers must be well armed? Because powerful enemies are bent on destroying them as spiritual persons. Regarding these enemies and the Christian’s fight against them, the apostle Paul wrote: “We have a wrestling, not against blood and flesh, but against the governments, against the authorities, against the world rulers of this darkness, against the wicked spirit forces in the heavenly places.” (Eph. 6:12) So ours is a fight against the Satanic powers of darkness, the Devil and his demons. Physical weapons and armor would be of no value in a battle against these superhuman spirits.
