The seventh beatitude revolves around “peace.” Jesus said, “Blessed are the peacemakers, for they shall be called sons of God” (Matthew 5:9, ESV). Jesus Himself was the ultimate peacemaker. Paul wrote, “And through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross” (Colossians 1:20, ESV). Christ’s death made it possible for us to have peace with God and should motivate us to pursue peace with others.
Osborne does a good job highlighting the vertical and horizontal dimensions of “peace” tied up in this verse. He commented:
This connotes both peace with God and peace between people—the latter flows out of the former. Jesus is the supreme peacemaker, who reconciles human beings with God through the cross (Col 1:20), so the supreme peacemaking is the proclamation of the gospel (Osborne, Matthew, Kindle Loc. 3352-3357).
We become peacemakers by proclaiming the gospel of Jesus Christ, the Supreme Peacemaker. And, we seek peace within the church and between the church and the world. All of this is connected to the gospel and our relationship to the One who made peace by his shed blood on the cross.
The result of being a peacemaker is being called a son of God. Carson wrote, “The peacemaker’s reward, then, is that he will be called a son of God. He reflects his heavenly Father’s wonderful peacemaking character” (Carson, The Sermon on the Mount, 27). Let us seek to demonstrate our familial relation to God by pursuing peace through gospel proclamation and gracious interaction with believers in the church and unbelievers outside the church.
