Verse 10: For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. This verse is condemning the Judaizers who were trying to get the Gentiles to submit to only portions or the law, e.g., circumcision, but not all of it. His point is that for one to place themselves back under the law in any circumstance is to place themselves back under the curse that comes with it because it brings death.
Verse 11: But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. His point is that no man is justified by the law in this current dispensation. Notice that the phrase is justified is in the present passive tense. This verse also requires a dispensational view.
Verse 12: And the law is not of faith: but, The man that doeth them shall live in them. The them is the verse is a reference to the law and is a quote from Leviticus 18:5 where it says, Ye shall therefore keep my statutes, and my judgments: which if a man do, he shall live in them: I am the LORD. Again, Paul's point is that people under the present dispensation are justified by faith and not by the keeping of the law.
In context, he is still addressing those who wanted to mix law with grace. However, as he said in verse 10, the law is not a pick and choose option, but an all or nothing proposition. He will further elaborate on this further in Galatians 5:2-4.
Again, these verses will not make sense, and even contradict, if they are not viewed through a dispensational lens, i.e., justification by works (Kingdom) or justification by faith (Grace).
Verse 13: Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: In this current dispensation, we have been redeemed from the curse of the law meaning that we do not have to keep it.
Notice that it says that Christ hath redeemed us from the curse of the law. The word redeemed means to purchase. The purchase was that Christ became the curse by his death. Remember that Christ redeemed the Jews from the curse of the law by taking the curse on himself. Who is the us in this context? The nation of Israel. Again, I have come to understand that pronouns are important in Bible interpretation.
The we/us in the epistle are the Jews (Galatians 2:15). The ye/you in the epistle are the Galatian gentiles. The ones that were redeemed were not ye/you, but we/us! Why is this important? - Because the Gentiles have never been under the curse of the law, ever, therefore, they did not need redemption from it. Instead, the Bible says that the Gentiles were aliens from the commonwealth of Israel in Ephesians 2:12-13, That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
If you still doubt that, keep reading.
Verse 14: That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith. This verse makes I clear that the nation of Israel was redeemed for two reasons. First, so that the blessing of Abraham might come on the Gentiles through Jesus Christ, and second, so that that we (the House of Israel) could receive the promise of the Spirit through faith which was fulfilled at Pentecost.
