7. Know and understand that it is [really] the people [who live] by faith who are [the true] sons of Abraham.
8. And the Scripture, foreseeing that God would justify (declare righteous, put in right standing with Himself) the Gentiles in consequence of faith, proclaimed the Gospel [foretelling the glad tidings of a Savior long beforehand] to Abraham in the promise, saying, In you shall all the nations [of the earth] be blessed. [Gen. 12:3.]
9. So then, those who are people of faith are blessed and made happy and favored by God [as partners in fellowship] with the believing and trusting Abraham.
10. And all who depend on the Law [who are seeking to be justified by obedience to the Law of rituals] are under a curse and doomed to disappointment and destruction, for it is written in the Scriptures, Cursed (accursed, devoted to destruction, doomed to eternal punishment) be everyone who does not continue to abide (live and remain) by all the precepts and commands written in the Book of the Law and to practice them. [Deut. 27:26.]
11. Now it is evident that no person is justified (declared righteous and brought into right standing with God) through the Law, for the Scripture says, The man in right standing with God [the just, the righteous] shall live by and out of faith and he who through and by faith is declared righteous and in right standing with God shall live. [Hab. 2:4.]
12. But the Law does not rest on faith [does not require faith, has nothing to do with faith], for it itself says, He who does them [the things prescribed by the Law] shall live by them [not by faith]. [Lev. 18:5.]
13. Christ purchased our freedom [redeeming us] from the curse (doom) of the Law [and its condemnation] by [Himself] becoming a curse for us, for it is written [in the Scriptures], Cursed is everyone who hangs on a tree (is crucified); [Deut. 21:23.]
14. To the end that through [their receiving] Christ Jesus, the blessing [promised] to Abraham might come upon the Gentiles, so that we through faith might [all] receive [the realization of] the promise of the [Holy] Spirit.
15. To speak in terms of human relations, brethren, [if] even a man makes a last will and testament (a merely human covenant), no one sets it aside or makes it void or adds to it when once it has been drawn up and signed (ratified, confirmed).
16. Now the promises (covenants, agreements) were decreed and made to Abraham and his Seed (his Offspring, his Heir). He [God] does not say, And to seeds (descendants, heirs), as if referring to many persons, but, And to your Seed (your Descendant, your Heir), obviously referring to one individual, Who is [none other than] Christ (the Messiah). [Gen. 13:15; 17:8.]
17. This is my argument: The Law, which began 430 years after the covenant [concerning the coming Messiah], does not and cannot annul the covenant previously established (ratified) by God, so as to abolish the promise and make it void. [Exod. 12:40.]
