John 17:21

1 Corinthians 12:12 NIV
Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ.

1 Corinthians 12:25-27 NIV
so that there should be no division in the body, but that its parts should have equal concern for each other. If one part suffers, every part suffers with it; if one part is honored, every part rejoices with it. Now you are the body of Christ, and each one of you is a part of it.

John 17:11 NIV
I will remain in the world no longer, but they are still in the world, and I am coming to you. Holy Father, protect them by the power of your name, the name you gave me, so that they may be one as we are one.

Philippians 1:27 NIV
Whatever happens, conduct yourselves in a manner worthy of the gospel of Christ. Then, whether I come and see you or only hear about you in my absence, I will know that you stand firm in the one Spirit, striving together as one for the faith of the gospel
