And as I've told YOU about a DOZEN times now - Eph. 2:10 says that the works that WE do in Christ were prepared FOR us by GOD.
In other words, my clueless friend - it's ALL the work of GOD. We simply cooperate with those works.
That's what makes us "sunergos" (co-workers) with God (1 Cor. 3:9, 2 Cor. 6:1).
That's why Paul was able to say under the inspiration of the Holy Spirit:
Col. 1:24
Now I rejoice in MY sufferings for your sake, and in my flesh I am filling up what is lacking in Christ’s afflictions for the sake of his body, that is, the church
Did Paul suffer and die for our sins?? NO - Christ did.
Paul is simply offering himself up as a living sacrifice for the Church (Rom. 12:1) and joining his sufferings with those of Christ (1 Pet. 4:13).
