Paul describes exactly what the mystery of the Church in the Old Testament was: that the Gentiles would be equally partakers of the Gospel of Christ. The Jews realized that they would be a light to the Gentiles (Isaiah 49: 6; 56: 6-7) but not that they would be equal with them! They thought that the Gentiles would be converts to Judaism. The mystery though as it has been revealed was for both to equally participate in the Church, God’s new creation. In order for both parties to be included each is required to accept the finished work of Christ on the cross. Nobody is automatically included or excluded because of race, heritage or previous religious experience. Blessings abound to those who know Christ Jesus as our Savior and Lord.
