and James said faith alone will not save...So what is the conclusion of the matter? Deeds done in faith from heart purity...
Galatians 3:12-18 (NKJV)
12 Yet the law is not of faith, but “the man who does them shall live by them.”
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.
The Changeless Promise
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.
The word promise in these verses, is referring to God's promise to Abraham in Genesis 12:1-3 that in him all the nations of the earth would be blessed.
This promise was given approximately 2000 B.C., preceding by centuries the Law of Moses which came at about 1450 B.C.
Judaizers argued that the giving of the law changed that original covenant of promise. Paul emphatically argues that it did not.
Paul argues that you can't change a covenant. A third party can't come along later and declare something agreed upon before to be null and void. God made the covenant with Abraham. The will cannot be broken.
The inheritance stands as God intended it to. It was a covenant of grace, based on God's promises to Abraham which Abraham received in faith.
Abraham did not initiate the covenant, buying from God His favor on the basis of all the good he would do. Paul writes:
The promises were spoken to Abraham and to his seed. The Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ. (Galatians 3:16)
both Old and New Testament statements declare without question that we are justified by faith, not by works. We are clothed in the righteousness which Christ earned on our behalf on the cross. Not by our feeble efforts at earning a righteousness based on our adherence to the Law.
