He ordered his troops to draw their swords and prepare for a massacre. They were four-hundred strong, and the world was about to witness unprecedented bloodshed. However, thanks to the delicate intervention of one wise woman, not a single casualty ensued. As king David prepared to slaughter an irrational Nabal and all his men, an amiable and perceptive woman named Abigail brought gifts to David and negotiated skillfully (1 Sam. 25:2-38). Immediately, David and his men put away their swords—never even meeting Nabal face-to-face—and Abigail saved countless lives through one risky act of peacemaking.

And this is precisely what Jesus instructs His followers to do in the seventh beatitude of the Sermon on the Mount: “Blessed are the peacemakers, for they shall be called sons of God” (Matt. 5:9). Simply put, a peacemaker is one who makes peace with others. Peacemakers do their best to live in harmony with those around them: “If possible, so far as it depends on you, live peaceably with all” (Rom. 12:18). Peacemakers don’t stir the pot or go to every fight they are invited to; instead, they bury the hatchet and build bridges. As Paul urged, “So then let us pursue what makes for peace and for mutual upbuilding” (Rom. 14:19).

Peacemaking also entails striving to bring peace between people who are at odds with one another. Instead of starting or stoking fires, peacemakers focus on extinguishing them. Like Moses, they try to resolve conflicts between people who are better off working together (Ex. 2:13-14). They put their best foot forward to mend fences, like Jonathan who sought to reconcile David and Saul (1 Sam. 19:1-7). Peacemakers work to assist others in making amends, such as Paul, who carefully and gently endeavored to establish peace between Euodia and Syntyche, and Philemon and Onesimus (Phil. 4:2-3; Philem. 8-10).

And the most principal prerequisite for peacemaking is being at peace with God. Enemies of the Lord cannot make peace because they are at odds with Him (Rom. 5:10). Only those who are God’s friends through faith in Christ’s saving work may enjoy this peace: “Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ” (Rom. 5:1). And this peace provides believers with a significant incentive to make peace with others. For, if God sacrificed much by sending His beloved Son to Golgotha to reconcile sinful man to Himself, how much more should saved sinners sacrifice comparatively little—like an awkward conversation or time spent in prayer—to restore relationships and live at peace with others? This is why peacemaking proves that one is a child of God: “for [peacemakers] shall be called sons of God” (Matt. 5:9b).
