The Letter to the Ephesians is a prison epistle. The key personalities of Ephesians are the Apostle Paul and Tychicus. It was written to encourage believers to walk as fruitful followers of Christ and to serve in unity and love in the midst of persecution.
In chapters 1 – 3, Paul teaches about the unity of believers. These are the truths and blessings that all believers have in common. He wrote that all Christians are “adopted as sons thorough Jesus Christ” (Eph 1: 5). All believers are, “redeemed through his blood” (Eph 1: 7), and sealed by the Holy Spirit (Eph 1: 13). Paul continues on to clear up one of the most misconceived and /or often ignored subject even to this day, that is, “salvation by grace”. He wrote that salvation is by the “GRACE” of God and that it is through “Faith”, and that no one can contribute to salvation, in any way, even with good deeds (Eph 2: 8-9).
In chapters 4 – 6, Paul encourages the believers to “walk in a manner worthy of the calling”. Every believer has a responsibility to live as servants of Jesus Christ. In these chapters, Paul teaches that it takes hard work to be in unity with others; and that we are to be “imitators of God” (Eph 5: 1). He mentions imperative truths and advice for well-functioning families, including husbands and wives who upon the oath of marriage becomes as “one flesh” (Eph 5: 31). In chapter 6, Paul instructs believers how to prepare for spiritual battle by dressing in the “full armour of God” (Eph 6: 11). Prayer is the key weapon of the Christian soldier. He emphasises his principle with the repeated statement “stand firm”.
