For Paul there are two kinds of people: Jews and Gentiles, or to put it another way, insiders and outsiders. The Prince of Peace is establishing peace where division and hostility once ruled unchallenged. In the Jerusalem temple, a stone wall separated Jewish from non-Jewish worshipers. According to Paul, the cross is God’s instrument to dismantle the wall, end the segregation, and make the two into one. God wants one people of God. That has been His plan all along.

Today walls continue to exist, erected strategically to separate people by race, religion, class, culture, and sex. Those who erect these walls, protect them, and maintain them will find that they are enemies of the gospel that brings all together into one worshiping family.
