Ephesians 2:14 (a) There is a separation between the Jew and the Gentile. To the Jew was given the oracles of GOD, but not to the Gentile. The Jews were redeemed by the blood of the Passover lamb, but the Gentiles were not. The Jews had GOD for their Father, but the Gentiles did not. By the coming of CHRIST and His sacrifice at Calvary, and His ascension to GOD the Father in His physical body, those differences have been broken down, and now all believers in CHRIST JESUS, both Jew and Gentile, are made one in CHRIST. Nothing now needs to separate the Jew and the Gentile. CHRIST JESUS unites us by the grace of GOD, and the work of the Holy Spirit.
