It was for this freedom that Christ set us free [completely liberating us]; therefore keep standing firm and do not be subject again to a yoke of slavery [which you once removed].
Notice, it is I, Paul, who tells you that if you receive circumcision [as a supposed requirement of salvation], Christ will be of no benefit to you [for you will lack the faith in Christ that is necessary for salvation]. Once more I solemnly affirm to every man who receives circumcision [as a supposed requirement of salvation], that he is under obligation and required to keep the whole Law. You have been severed from Christ, if you seek to be justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing with God] through the Law; you have fallen from grace [for you have lost your grasp on God’s unmerited favor and blessing]. For we [not relying on the Law but] through the [strength and power of the Holy] Spirit, by faith, are waiting [confidently] for the hope of righteousness [the completion of our salvation]. For [if we are] in Christ Jesus neither circumcision nor uncircumcision means anything, but only faith activated and expressed and working through love.
You were running [the race] well; who has interfered and prevented you from obeying the truth? This [deceptive] persuasion is not from Him who called you [to freedom in Christ]. A little leaven [a slight inclination to error, or a few false teachers] leavens the whole batch [it perverts the concept of faith and misleads the church]. I have confidence in you in the Lord that you will adopt no other view [contrary to mine on the matter]; but the one who is disturbing you, whoever he is, will have to bear the penalty. But as for me, brothers, if I am still preaching circumcision [as I had done before I met Christ; and as some accuse me of doing now, as necessary for salvation], why am I still being persecuted [by Jews]? In that case the stumbling block of the cross [to unbelieving Jews] has been abolished. I wish that those who are troubling you [by teaching that circumcision is necessary for salvation] would even [go all the way and] castrate themselves!
