Paul’s emphasis is the unity of Gentiles and Jews. That was the big dividing line early in the church.

We are one in Christ. There is neither Jew nor Greek in Christ. The Gentiles become fellow citizens in the commonwealth of Israel.

We are God’s chosen children. We don’t replace Israel, but we are joined to Israel as God’s chosen children.

When we were strangers, we were without hope. We didn’t have the covenant promises of Israel until God came to us and brought us near to Himself and to all those who are in His Body.

In bringing us to Himself, He reconciled us to God and to each other. One of the ways He did that was by “abolishing the law of commandments expressed in ordinances.” Jesus said He didn’t come to abolish the law but fulfill it. Jesus perfectly fulfilled the law of love. Jesus perfectly fulfilled the law of holiness and righteousness. He did away with the need for constant blood sacrifice because He became our perfect sacrifice. He did away with the need for cleansing and holiness rituals, like not eating with Gentiles, because He made us holy. He cleansed us by His blood and keeps us clean by the power of His Spirit at work in us.

Through the cross and resurrection of Jesus, we all have access to the Father. The same Spirit lives in all of us, giving us instant fellowship with one another.

Again, this isn’t just about you or me. It’s about us. It’s about all believers coming together as one. We are joined together. We are being built into a holy temple with Christ as the cornerstone, our firm foundation. We, all of us as one, are being built together into a dwelling place for God. He is in each of us. But we aren’t in the fullness of His indwelling, until He’s filling all of us as one.
