Epistles: Ephesians 3:1-12 – The Divine Mystery in Christ

Key text: “This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Jesus Christ” (Ephesians 3:6).

Lesson objective:To understand that Paul, the commissioned apostle to the Gentiles, now imprisoned in Rome on their account, is God’s chosen instrument to disclose God’s divine plan of the hidden mystery in Christ through the message of the gospel given to him by revelation.

Introduction: The apostle Paul had an enormous missionary vision that began with humble beginnings. It was at Antioch in Syria where prayer was made to send Paul and Barnabas on their first missionary journey to Asia Minor (Acts 13:1-3). Within a few years Paul was to make a second and a third journey, moving from Asia Minor into Greece. His mission to the Gentiles flourished with churches being established in nearly all the major cities of the time (Acts 17:6). He hastened to reach Rome itself, the capitol of the world-ruling Roman Empire, with one focus in mind: to preach the gospel!

Paul’s Gentile mission field was fertile and ready for the harvest. The Holy Spirit worked in Paul in a mighty way. Paul’s plan was to establish himself in the west in Rome as he had done in the east in Antioch (Romans 15:14-32). He would blaze a trail from Rome all the way across the Western Empire to Spain – and planting churches in every place he would stay along the way. However, God had other plans for Paul. Paul was to go to prison on account of his preaching to the Gentile world; and eventually die a martyr’s death for the glory of God. Paul did arrive at Rome, but in chains awaiting trial (Acts 28:16-30). This is how the inspired book of Acts ends.

Nevertheless, that the power of God might be manifest even while his greatest apostle is in chains, Paul penned what are termed the “prison epistles.” Our letter to the Ephesians stands among them. To the glory of Christ and future missionary endeavors to come across the ages, the divine mystery in Christ is fully disclosed and preserved in the written Word of the new covenant Scriptures. This mystery was not fully unveiled in the past, even though glimpses of it are present in the old covenant Scriptures. However, the full implications of Christ’s death and resurrection were made known only through direct revelation from God to the apostles and prophets (Ephesians 3:1-5).

The chosen champion of the Gentile mission is the apostle Paul (vv. 7-12). It is through his pen that we learn of the amazing grace of Christ’s law-free gospel to the Gentiles. The mystery was this: How could law-observing Jews ever be reconciled with law-free Gentiles? Would the Gentiles have to accept circumcision as a sign of entrance into the covenant and submit themselves to Moses? Paul’s answer is emphatically: NO!

The divine mystery in Christ has revealed that believing Gentiles are on the very same footing as Jewish believers: First, Gentiles as well as Jews are free from the law; the old covenant law is no longer binding on believers in Christ (2:14-15). Second, Gentiles are co-heirs with believing Jews (3:6a). Third, through Christ both are made into one body (v. 6b). And finally, believing Jews and Gentiles do not exist in two different covenants, but share equally in the one and same new covenant promise in Christ (v. 6c). Amen.
