1Foolish Galatians, who has bewitched you not to obey the truth, before whose eyes Jesus Christ was openly portrayed among you as crucified? 2I just want to learn this from you: Did you receive the Spirit by the works of the law, or by hearing of faith? 3Are you so foolish? Having begun in the Spirit, are you now completed in the flesh? 4Did you suffer so many things in vain, if it is indeed in vain? 5He therefore who supplies the Spirit to you and does miracles among you, does he do it by the works of the law, or by hearing of faith? 6Even so, Abraham “believed God, and it was counted to him for righteousness.” 7Know therefore that those who are of faith are children of Abraham. 8The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, “In you all the nations will be blessed.” 9So then, those who are of faith are blessed with the faithful Abraham.
10For as many as are of the works of the law are under a curse. For it is written, “Cursed is everyone who doesn’t continue in all things that are written in the book of the law, to do them.” 11Now that no man is justified by the law before God is evident, for, “The righteous will live by faith.” 12The law is not of faith, but, “The man who does them will live by them.”
13Christ redeemed us from the curse of the law, having become a curse for us. For it is written, “Cursed is everyone who hangs on a tree,” 14that the blessing of Abraham might come on the Gentiles through Christ Jesus, that we might receive the promise of the Spirit through faith.
15Brothers, speaking of human terms, though it is only a man’s covenant, yet when it has been confirmed, no one makes it void or adds to it. 16Now the promises were spoken to Abraham and to his offspring. He doesn’t say, “To descendants”, as of many, but as of one, “To your offspring”, which is Christ. 17Now I say this: A covenant confirmed beforehand by God in Christ, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect. 18For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.
19Then why is there the law? It was added because of transgressions, until the offspring should come to whom the promise has been made. It was ordained through angels by the hand of a mediator. 20Now a mediator is not between one, but God is one.
21Is the law then against the promises of God? Certainly not! For if there had been a law given which could make alive, most certainly righteousness would have been of the law. 22But the Scripture imprisoned all things under sin, that the promise by faith in Jesus Christ might be given to those who believe.
23But before faith came, we were kept in custody under the law, confined for the faith which should afterwards be revealed. 24So that the law has become our tutor to bring us to Christ, that we might be justified by faith. 25But now that faith has come, we are no longer under a tutor. 26For you are all children of God, through faith in Christ Jesus. 27For as many of you as were baptized into Christ have put on Christ. 28There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus. 29If you are Christ’s, then you are Abraham’s offspring and heirs according to promise.
One might think that the particular ancestors of Jesus might not be important since the important thing is that God entered into human existence as an actual human in order to become the sacrifice for the sins of humanity, providing salvation to those who believe in Him.
However, the mission of Jesus was multi-faceted. This becomes obvious in the New Testament since Matthew's Gospel carefully lists His genealogy from two historic figures in Jewish history, namely Abraham and David. The former becomes the basis of Jesus providing salvation for Gentiles as well as Jews, according to Paul's argument in Galatians 3:26-29, fulfilling the third prong of the Abrahamic Covenant. In Romans 1:3, Paul states that Jesus, according to lineage, connects to David the King and so has a right to reign as a descendant of David over Israel and inheritor of the Davidic Covenant. This reign has not begun but will upon Jesus' return to the earth and will last forever (see 2 Sam 7:8-17). Some view the reign of Messiah as spiritually beginning as a Davidic king, but His current reign is not political in nature and not physically on the earth. The current reign of Messiah Jesus is after the order of Melchizedek, a priestly function for the salvation of humanity, but the Davidic reign will be on the earth in a political manner.1
