Galatians 2:7
But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter; But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
God entrusted to Paul the gospel for the uncircumcised, especially the Gentiles, just as He entrusted to Peter the gospel for the circumcised, especially the Jews, giving each a distinct field of labor. Paul's broad mission to the Gentiles was presented to him with remarkable distinctness when he received his commission from God while praying in the temple. To prepare him for this extensive and important work God brought him into close connection with Himself and opened before his enraptured vision a glimpse of the beauty and glory of heaven. The corresponding Jewish field was to be worked at home with Jerusalem as the center, where Peter with James and John were to preach Christ among their own countrymen. From that center they could reach Jews of all tongues who came there for the festivals.
When the Jerusalem apostles saw this God-appointed division, they recognized Paul's commission and accepted him as a fellow worker, not inferior to them in position or authority. Although Peter was the apostle of the circumcision, God in His wisdom, knowing the end from the beginning, chose him to do the first work among the Gentiles and to lead out in proclaiming the gospel to them. He was best able to do it without friction and to remove the prejudice existing among Jewish Christians, and Peter accepted the interpretation of the vision God gave him. This recognition supported leaving Gentile believers free from the obligations of the ceremonial law. Peter himself never attempted to force its rites upon Gentile converts. These distinct appointments were part of God's providence, and both apostles later bore witness for Christ in Rome and died there, their deaths helping to bring about a great harvest of Christians and martyrs.
