Here is the mystery. Because of the good news, God’s promises are for Gentiles as well as for Jews. Both groups are parts of one body. They share in the promise. It belongs to them because they belong to Christ Jesus.
He makes the whole body grow and build itself up in love. Under the control of Christ, each part of the body does its work. It supports the other parts. In that way, the body is joined and held together.
They aren’t connected anymore to the head, who is Christ. But the whole body grows from the head. The muscles and tendons hold the body together. And God causes it to grow.
Here there is no Gentile or Jew. There is no difference between those who are circumcised and those who are not. There is no rude outsider, or even a Scythian. There is no slave or free person. But Christ is everything. And he is in everything.
