Galatians 3:14

That upon the Gentiles might come the blessing of Abraham in Christ Jesus; that we might receive the promise of the Spirit through faith.

In Christ Jesus ... This is the cornerstone and foundation of the gospel Paul (and all the apostles) preached. The Gentiles will be blessed, along with Abraham, "in Christ," thus becoming technically part of Christ's spiritual body, therefore truly of "the seed singular" of Abraham, which is Christ. See under Galatians 3:16, where Paul elaborated this.

Through faith ... Every scholar on earth knows that the article precedes "faith" in this place in the Greek New Testament, and that the only honest translation is "through the faith," meaning through the Christian religion. See Emphatic Diaglott, Nestle Greek Text, or any dependable Greek-English rendition of the New Testament. Foy E. Wallace also pointed this out. The attempted perversion of the meaning of this chapter is so extensive as to be phenomenal. The last thing on earth that this passage could mean is that the Gentiles shall be saved through trust/faith alone, which by any definition can be nothing but a subjective personal experience without any merit or trustworthiness whatever.
