Faith, the key to the Gospel. Paul is telling the Galatians that faith not works is the key issue here. He points out that hearing with faith was the way you were saved and that the false gospel of works is not consistent with the teachings of Christ.
Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh?Galatians 3:3
Paul is a little riled up at the Galatians for believing this false Gospel. He also gives us the answer to how those before Christ are saved (if you needed more confirmation) he describes Abraham’s faith in God and counting it as righteousness. He also connects his ministry to the gentiles back to the fulfillment of God’s promises to Abraham.
And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, “In you shall all the nations be blessed.”Galatians 3:8
We gentiles are the blessed nations and how true it is God has truly blessed us and especially me, more than I deserve.
