Galatians 3 “6 Even so, Abraham “believed God, and it was counted to him for righteousness.” 7 Know therefore that those who are of faith are children of Abraham. 8 The 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.” 9 So then, those who are of faith are blessed with the faithful Abraham.“
The blessing of Abraham is the gift of righteousness received by faith in Christ.
But God put Israel under the Law for 1500 years. The law demanded perfection and no man could be righteous by keeping the Law.
Galatians 3 “10 For 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.” 11 Now that no man is justified by the law before God is evident, for, “The righteous will live by faith.” 12 The law is not of faith, but, “The man who does them will live by them.”
The main reason for God to give the Law was to exposes sins that demanded judgment.
Therefore it was only under the Law, that Jesus Christ died for our sins and redeemed us from judgment and give us the blessing of Abraham.
Without the Law, salvation could not come. The Law imputed all our sins on Christ’s body on the cross so that the blessing of Abraham (righteousness) is given to all people by faith in Christ.
Galatians 3″13 Christ 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 on the Gentiles through Christ Jesus, that we might receive the promise of the Spirit through faith.”
God did not give the Law to change the promise of Abraham. The Law was a temporary covenant, until Jesus died for our sins to bring salvation to all nations.
Galatians 3 “17 Now 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. 18 For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.”
19 Then 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. 20 Now a mediator is not between one, but God is one. 21 Is 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. 22 But the Scripture imprisoned all things under sin, that the promise by faith in Jesus Christ might be given to those who believe.”
The Law was fulfilled on the cross so that righteousness is given to all who believe in Christ.
Galatians 3 “23 But before faith came, we were kept in custody under the law, confined for the faith which should afterwards be revealed. 24 So that the law has become our tutor to bring us to Christ, that we might be justified by faith. 25 But now that faith has come, we are no longer under a tutor. 26 For you are all children of God, through faith in Christ Jesus.“
Once we believe in Christ, we are not under law or its condemnation. We are children of God by faith in Christ – we are righteous, holy, blameless, perfect, without condemnation in Christ.
