Barnes New Testament Notes

Verse 30. It is one God. The same God; there is but one, and his plan is equally fitted to Jews and Gentiles.

The circumcision. Those who are circumcised -- the Jews.

The uncircumcision. Gentiles; all who were not Jews.

By faith -- through faith. There is no difference in the meaning of these expressions. Both denote that faith is the instrumental cause of justification, or acceptance with God.

{e} "which shall justify" Ga 3:8,28
