But if, while we seek to be justified in Christ [by faith], we ourselves are found to be sinners, does that make Christ an advocate or promoter of our sin? Certainly not!

So then, does He who supplies you with His [marvelous Holy] Spirit and works miracles among you, do it as a result of the works of the Law [which you perform], or because you [believe confidently in the message which you] heard with faith?

For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”

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.

This is what I mean: the Law, which came into existence four hundred and thirty years later [after the covenant concerning the coming Messiah], does not and cannot invalidate the covenant previously established by God, so as to abolish the promise.

Now what I mean [when I talk about children and their guardians] is this: as long as the heir is a child, he does not differ at all from a slave even though he is the [future owner and] master of all [the estate];

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.”
