In the Cross of our Lord Jesus Christ

Galatians 6:14-18 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. For in Christ Jesus neither circumcision availed any thing, nor uncircumcision, but a new creature. And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God. From henceforth let no man trouble me: for I bear in my body the marks of the Lord Jesus. Brethren, the grace of our Lord Jesus Christ be with your spirit. Amen. To the Galatians written from Rome. 

‘God forbid that I should glory.’ The last occurrence of this phrase. Glorification must always be unto God, never to oneself.

‘Save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.’ Others may glory in circumcision, rituals, and a great show of converts to an easy religion, but I will glory only in the cross of Jesus Christ. Those former things are empty, worthless and crucified to them by the cross. Nothing avails anything, but a new creation in Christ (6:15; 2Cor. 5:17-18; Eph. 2:10; 4:23-24; Col. 3:10).

‘Rule’ [Greek: kanon] canon, rule of Christianity. This rule is that redemption is through Jesus Christ apart from circumcision, sabbath-keeping, and all the law of Moses (1:6-8; 2:15-21; 3:13-14, 19-29; 4:1-10; 5:1-7, 11; 6:12-15).

‘And upon the Israel of God.’ This Israel of God is made up of the true Jews who accept this rule along with the Gentiles (Rom. 2:29; 9:6).

‘Marks’ [Greek: stigma] Slaves were branded. So, Paul, as a slave, bore the marks of his slave service. They gloried in their circumcision mark (6:12-13), but Paul said he will glory in his marks of suffering for Jesus Christ (2Cor. 11:23-28).
