Colossians 1:24-25

24At this time, I am suffering on your behalf, but I am still happy. Christ himself suffered on behalf of his people, the church. Now, while I live in my human body, I also suffer. I continue to receive the pain that Christ received, so that it may be complete. In that way, I help the church, which is like Christ's own body.

25I have become God's servant, so that I can help the church. God chose me to do that. He chose me to explain his message to you completely.
