Knowing this, that our old man is crucified with [him], that the body of sin might be destroyed, that henceforth we should not serve sin. (6:6)

--Galations--

I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. (2:20)

And they that are Christ's have crucified the flesh with the affections and lusts. (5:24)

But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world. (6:14)
