As we have said before, so I now say again, if anyone is preaching to you a gospel different from that which you received [from us], let him be condemned to destruction!

But from those who were of high reputation (whatever they were—in terms of individual importance—makes no difference to me; God shows no partiality—He is not impressed with the positions that people hold nor does He recognize distinctions such as fame or power)—well, those who were of reputation contributed nothing to me [that is, they had nothing to add to my gospel message nor did they impose any new requirements on me].

[I went on to say] “We are Jews by birth and not sinners from among the Gentiles;

Now it is clear that no one is justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing] before God by the Law, for “The righteous (the just, the upright) shall live by faith.”

But the Law does not rest on or require faith [it has nothing to do with faith], but [instead, the Law] says, “He who practices them [the things prescribed by the Law] shall live by them [instead of faith].”

Now the promises [in the covenants] were decreed to Abraham and to his seed. God does not say, “And to seeds (descendants, heirs),” as if [referring] to many [persons], but as to one, “And to your Seed,” who is [none other than] Christ.

Tell me, you who are bent on being under the Law, do you not listen to [what] the Law [really says]?

But what does the Scripture say?

“Cast out the bondwoman [Hagar] and her son [Ishmael],
For never shall the son of the bondwoman be heir and share the inheritance with the son of the free woman.”

But I say, walk habitually in the [Holy] Spirit [seek Him and be responsive to His guidance], and then you will certainly not carry out the desire of the sinful nature [which responds impulsively without regard for God and His precepts].
