“For as many as are out of works of Law, [these] are under a curse. For it has been written, Cursed [is] everyone who does not continue in all the things having been written in the book of the Law, to do them. And that no one is justified by Law before God [is] clear because, The just shall live by faith. But the Law is not of faith, but, The man doing these things shall live in them. Christ redeemed us from the curse of the Law, having become a curse for us; for it has been written, Cursed [is] everyone having been hung on a tree; that the blessing of Abraham might be to the nations in Christ Jesus, that we might receive the promise of the Spirit through faith. Brothers, I speak according to man, a covenant having been ratified, even [among] mankind, no one sets aside or adds to [it]. But the promises were spoken to Abraham and to his Seed (it does not say, And to seeds, as of many, but as of one, And to your Seed, which is Christ). And I say this, A covenant having been ratified before to Christ by God, [the] Law coming into being four hundred and thirty years after, does not annul the promise, so as to abolish [it]. For if the inheritance [is] of Law, [it is] no more of promise; but God has given [it] to Abraham through promise. Why the Law then? It was for the sake of transgressions, until the Seed should come, to whom it had been promised, being ordained through angels in a mediator’s hand. But the Mediator is not of one, but God is one. Then is the Law against the promises of God? Let it not be! For if a law had been given which had been able to make alive, indeed righteousness would have been out of Law. But the Scripture locked up all under sin, that the promise by faith of Jesus Christ might be given to the ones believing. But before the coming of faith, we were guarded under Law, having been locked up to the faith being about to be revealed. So that the Law has become a trainer of us [until] Christ, that we might be justified by faith. But faith coming, we are no longer under a trainer; for you are all sons of God through faith in Christ Jesus” (Galatians 3:10-26).
The Christian Confession of Faith expresses the harmony between the law and the gospel well:
“The function of God’s law is to show forth God’s perfect standard of righteousness that His people may:
1. Learn their natural inability to meet that standard, [Deu 9:4-6; Psa 130:3; Isa 64:6; Dan 9:5-11; Rom 3:19-20; 5:13,20; 7:7-13; Gal 3:10-12; 4:24-25; Jam 2:10-11]
2. Rest in a Substitute who would and did meet that standard on their behalf, [Psa 32:1-2; 34:19-20; 130:4; Isa 53:11; Joh 8:56; Rom 3:21-22; 7:24-25; 2Co 5:21; Gal 3:19; Heb 7:25-27; 11:24-28; 1Pe 2:21-24]
3. And strive to obey Him out of love, thankfulness, and a desire to glorify Him. [Exo 20:20; Deu 6:1-25; 8:1-18; 10:12-13; 13:4; Jos 1:8; 23:6; 1Sa 15:22; Psa 1:2; 119:2,4-6,10-11,16,55,60,72,77,97,109,112,129,166-168; Ecc 12:13; Mat 22:37-40; Joh 14:15,21; Rom 6:1-2,11-13; 1Co 6:20; Eph 5:15-21; Heb 12:28-29]
