Galatians 3:10–18 (NKJV)
10 For as many as are of the works of the law are under the curse; for it is written, “Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.” 11 But that no one is justified by the law in the sight of God is evident, for “the just shall live by faith.” 12 Yet the law is not of faith, but “the man who does them shall live by them.”Galatians 3:10-14
13 Christ has 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”), 14 that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith.
Paul identifies the law not as a means to salvation, but rather a requirement which no one can fulfill. The law enforces the curse levied for sin. Faith is the means whereby grace is appropriated, and by which the faith-filled live. Through Christ, the blessing of Abraham came come to the Gentiles as well. Jesus made a way for anyone to be forgiven and set free from the curse of the law.
15 Brethren, I speak in the manner of men: Though it is only a man’s covenant, yet if it is confirmed, no one annuls or adds to it. 16 Now to Abraham and his Seed were the promises made. He does not say, “And to seeds,” as of many, but as of one, “And to your Seed,” who is Christ. 17 And this I say, that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect. 18 For if the inheritance is of the law, it is no longer of promise; but God gave it to Abraham by promise.Galatians 3:15-18
Abraham was the patriarch of the Jews, the father of a nation if you will. The Abrahamic Covenant provided blessings to Abraham and blessings to all who blessed him. Christ was Abraham’s seed, and carried out the work of fulfilling the law and the covenant of Abraham. The promise of God superseded the law, superseded the failures of millions of people trying to serve God, overcame the weaknesses of man, and provided salvation to people of all races and colors through Jesus Christ. The main principle to be remembered here is that the just shall live by faith. No one can be good enough, and no one is deserving enough for salvation. However, grace comes through faith; grace to be saved, and grace to continue to live for Christ. You live by faith: forgiven, holy, separated from evil and unto God. Be forgiven by grace, be made holy by grace, continue holy living by grace. be transformed by grace. Live by faith!
