31 For this cause I Paul, the prisoner of Christ Jesus in behalf of you Gentiles,— 2 if so be that ye have heard of the dispensation of that grace of God which was given me to you-ward; 3 how that by revelation was made known unto me the mystery, as I wrote before in few words, 4 whereby, when ye read, ye can perceive my understanding in the mystery of Christ; 5 which in other generation was not made known unto the sons of men, as it hath now been revealed unto his holy apostles and prophets in the Spirit;
Matthew Henry's Commentary on Ephesians 3:1-5
Commentary on Ephesians 3:1-7
(Read Ephesians 3:1-7)
For having preached the doctrine of truth, the apostle was a prisoner, but a prisoner of Jesus Christ; the object of special protection and care, while thus suffering for him. All the gracious offers of the gospel, and the joyful tidings it contains, come from the rich grace of God; it is the great means by which the Spirit works grace in the souls of men. The mystery, is that secret, hidden purpose of salvation through Christ. This was not so fully and clearly shown in the ages before Christ, as unto the prophets of the New Testament. This was the great truth made known to the apostle, that God would call the Gentiles to salvation by faith in Christ. An effectual working of Divine power attends the gifts of Divine grace. As God appointed Paul to the office, so he qualified him for it.
