What does verse 8 say about God working in Peter and Paul?
Verse 8 declares that the same God who wrought effectually in Peter for the apostleship of the circumcision, meaning the Jews, was mighty in Paul toward the Gentiles. It stresses that God never changes, yet He worked through Peter to Israel and through Paul to the Gentiles.
Les explains that when they saw the gospel of the uncircumcision, that is, the Gentiles, was committed to Paul, just as the gospel of the circumcision, for the Jew, was committed to Peter, they understood these were two separate entities. Verse 8 then says the same God who wrought effectually in Peter to the apostleship of the circumcision was mighty in Paul to the Gentiles. Les emphasizes that God never changes, but He was working through Peter to Israel and Paul to the Gentiles.
