15:8-13 Christ fulfilled the prophecies and promises relating to the Jews, and the Gentile converts could have no excuse for despising them. The Gentiles, being brought into the church, are companions in patience and tribulation. They should praise God. Calling upon all the nations to praise the Lord, shows that they shall have knowledge of him. We shall never seek to Christ till we trust in him. And the whole plan of redemption is suited to reconcile us to one another, as well as to our gracious God, so that an abiding hope of eternal life, through the sanctifying and comforting power of the Holy Spirit, may be attained. Our own power will never reach this; therefore where this hope is, and is abounding, the blessed Spirit must have all the glory. All joy and peace; all sorts of true joy and peace, so as to suppress doubts and fears, through the powerful working of the Holy Spirit.
8-12. Now—"For" is the true reading: the apostle is merely assigning an additional motive to Christian forbearance.
I say that Jesus Christ was—"hath become"
a minister of the circumcision—a remarkable expression, meaning "the Father's Servant for the salvation of the circumcision (or, of Israel)."
for the truth of God—to make good the veracity of God towards His ancient people.
to confirm the—Messianic
promises made unto the fathers—To cheer the Jewish believers, whom he might seem to have been disparaging, and to keep down Gentile pride, the apostle holds up Israel's salvation as the primary end of Christ's mission. But next after this, Christ was sent.
