Galatians 6:15
“For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.”
For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.
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 availeth 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.
