Ephesians is a letter unity. In this letter Paul reminds the Ephesians that in Christ there is unity of heart and spirit. He speaks of the redemption found only in Christ, the grace that saved us apart from works so that no one could boast, and of the fact that Jews and Gentiles are saved the same way and are part of one body of believers. Paul exhorts them to put their old ways behind them and walk in the newness of life in Christ. He addresses husbands, wives, parents, children, bondservants, and masters to take their role and honor God in it. Finally, Paul reminds them to put on the whole armor of God is order to accomplish all this.
