The main theme of Ephesians is "the Church, the Body of Christ." As a prisoner for the Lord, then, I urge you to live a life worthy of the calling you have received. Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace. The Church is to maintain the unity in practice which Christ has brought about. the theme may be stated pragmatically as "Christians, get along with each other! Maintain the unity practically which Christ has effected positionally by his death." Another major theme in Ephesians is the keeping of Christ's body (that is, the Church) pure and holy. Therefore be imitators of God, as beloved children. And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God. the author of the Epistle to the Ephesians gives practical advice in how to live a holy, pure, and Christ-inspired lifestyle. Many devotional thoughts and sermons that are addressed to the practically minded individual have been drawn from this section of the New Testament, due to its nature as being good for application studies.
