We are part of Jesus

We are part of Jesus.

"Saul, Saul. Why are you persecuting me?" (when Paul was persecuting the church?)
It's because Jesus doesn't see the church, or its members, as separate from Himeself. We're one with Him. We're part of Jesus now.

For even as the body is one and yet has many members, and all the members of the body though they are many, are one body, so also is Christ.

Paul isn't comparing the Body of Christ to a human body; he's comparing Christ to a human body. As the body has many members, so also does Christ. Christ has made Himself a corporate being. You are part of that being. So am I.
