Paul, a prisoner for the testimony of Jesus, declares his knowledge of what had been a mystery from all ages, that the Gentiles should be fellow heirs and of the same body with the Jews, Eph 3:1-6. Which doctrine he was made a minister, that he might declare the unsearchable riches of Christ, and make known to principalities and powers this eternal purpose of God, Eph 3:7-12. He desires them not to be discouraged on account of his tribulations, Eph 3:13. His prayer that they might be filled with all the fullness of God, Eph 3:14-19. His doxology, Eph 3:20, Eph 3:21.
