Ephesians is perhaps the most majestic, rich and profound of Paul’s epistles. It has been called “the Grand Canyon of Scripture” and abounds in powerful superlatives. Paul writes with extraordinary cohesiveness to the church at Ephesus while he is “a prisoner of Jesus Christ” (Eph. 3:1 & 4:1). He is suffering particular hardships (3:13) and views himself as an “ambassador in chains” (6:20). However, the epistle contains few other particulars regarding the writer or his readers. There is a marked absence of biographical references or personal greetings. There are a few allusions to false teachings, but Paul elaborates on no specific doctrinal problem. This helps explain the dynamics of the epistle, for its contents are solely for the edification of his readers. Ephesians differs from other Pauline letters, for his focus is on the universal Church rather than on issues within a local church. The interwoven theme is the unification of Believers who form a spiritual society within a secular society. Paul motivates his readers to closer unity by reminding them of Christ’s eternal purpose.
