Galatians 5:2-6 New King James Version (NKJV)

² Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing. ³ And I testify again to every man who becomes circumcised that he is ^[a]a debtor to keep the whole law. ⁴ You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace. ⁵ For we through the Spirit eagerly wait for the hope of righteousness by faith. ⁶ For in Christ Jesus neither circumcision nor uncircumcision avails anything, but faith working through love.
