Ever since Genesis 3, it has been hard for people to get along. We’re all so different, and, because of our fallenness, those differences can annoy us, threaten us, and make us suspicious of one another. In jealousy, envy, and pride, we tend to think, say, and do nasty things to each other, making life unpleasant at times.

In the first century, there were two groups of people who didn’t get along very well—Jews and Gentiles. The Jews were descendants of Abraham through Isaac and Jacob. The Gentiles were everybody else. Both latent and overt hostility marked their relationship over the centuries. Paul addresses that enmity in Ephesians 2, and he talks about what God has done to rectify it. The solution he offers is still relevant today because the world is more polarized now than ever. In recent years we have witnessed a growing hostility between races, classes, genders, and political parties. The tension is exhausting and disillusioning.

How can God take widely diverse and disparate people and put them successfully into one new group? Paul’s answer is Jesus. Why? Because “he himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility, by abolishing in his flesh the law with its commandments and regulations. His purpose was to create in himself one new man out of the two, thus making peace” (Eph 2:14-15).

Paul argues that the source of alienation between Jew and Gentile—God’s law—was put on the shelf (2:15a) because the source of reconciliation—God’s Son—was put on the cross (2:13b, 16b). Human beings may be hostile to each other, but God treated his perfect Son as if he were all the world’s hostility rolled into one. And when Christ died on the cross, the Father regarded the hostility itself as having died, too. God’s purpose was to create one new humanity out of the two—a horizontal hostility replaced with horizontal peace (2:15b).

The result is that irreligious people (like the Gentiles, who thought they are “far off”) can now hear and believe the gospel of peace (2:17a). Religious people (like the Jews, who thought they are already near) can hear and believe that same gospel (2:17b). All are “far off” because of sin, but all can “draw near” now because of Jesus. God is wise in this regard. All who draw near to him wind up drawing near to each other, too. Indeed, the only way to fully experience the God who is community is to participate fully in his new community—the church.

That’s not always easy because we’re all different. But believers who draw near to God bear the marks of unity in diversity. That’s why Paul cites the Trinity two times in this passage (2:18, 22). God the Father, God the Son, and God the Holy Spirit are the ultimate model for the church—a community of truth, love, and unity in diversity.
