Galatians 5:6-10

For in Christ Jesus neither circumcision nor uncircumcision means anything, but faith working through love. You were running well; who hindered you from obeying the truth? This persuasion did not come from Him who calls you. A little leaven leavens the whole lump of dough. I have confidence in you in the Lord that you will adopt no other view; but the one who is disturbing you will bear his judgment, whoever he is.
