Christ was “a minister of the circumcision for the truth of
God, to confirm the promises made unto the fathers, and that the
Gentiles might glorify God for His mercy” (Rom. 15:8,9).  The Jew was
heir to “the promises”; and in fulfillment of these Christ became “a minister
of the circumcision”:the Gentiles, being “strangers from the covenants of
promise,” (Eph. 2:12) are absolutely dependent upon mercy.
