1Be therefore imitators of God, as beloved children. 2Walk in love, even as Christ also loved us and gave himself up for us, an offering and a sacrifice to God for a sweet-smelling fragrance.
3But sexual immorality, and all uncleanness or covetousness, let it not even be mentioned among you, as becomes saints; 4nor filthiness, nor foolish talking, nor jesting, which are not appropriate, but rather giving of thanks.
5Know this for sure, that no sexually immoral person, nor unclean person, nor covetous man (who is an idolater), has any inheritance in the Kingdom of Christ and God.
6Let no one deceive you with empty words, for because of these things the wrath of God comes on the children of disobedience. 7Therefore don’t be partakers with them. 8For you were once darkness, but are now light in the Lord. Walk as children of light, 9for the fruit of the Spirit is in all goodness and righteousness and truth, 10proving what is well pleasing to the Lord. 11Have no fellowship with the unfruitful deeds of darkness, but rather even reprove them. 12For it is a shame even to speak of the things which are done by them in secret. 13But all things, when they are reproved, are revealed by the light, for everything that reveals is light. 14Therefore he says, “Awake, you who sleep, and arise from the dead, and Christ will shine on you.”
15Therefore watch carefully how you walk, not as unwise, but as wise, 16redeeming the time, because the days are evil. 17Therefore, don’t be foolish, but understand what the will of the Lord is. 18Don’t be drunken with wine, in which is dissipation, but be filled with the Spirit, 19speaking to one another in psalms, hymns, and spiritual songs; singing and making melody in your heart to the Lord; 20giving thanks always concerning all things in the name of our Lord Jesus Christ to God, even the Father; 21subjecting yourselves to one another in the fear of Christ.
22Wives, be subject to your own husbands, as to the Lord. 23For the husband is the head of the wife, as Christ also is the head of the assembly, being himself the savior of the body. 24But as the assembly is subject to Christ, so let the wives also be to their own husbands in everything.
25Husbands, love your wives, even as Christ also loved the assembly and gave himself up for her, 26that he might sanctify her, having cleansed her by the washing of water with the word, 27that he might present the assembly to himself gloriously, not having spot or wrinkle or any such thing, but that she should be holy and without defect. 28Even so husbands also ought to love their own wives as their own bodies. He who loves his own wife loves himself. 29For no man ever hated his own flesh, but nourishes and cherishes it, even as the Lord also does the assembly, 30because we are members of his body, of his flesh and bones. 31“For this cause a man will leave his father and mother and will be joined to his wife. Then the two will become one flesh.” 32This mystery is great, but I speak concerning Christ and the assembly. 33Nevertheless each of you must also love his own wife even as himself; and let the wife see that she respects her husband.
Paul’s moral instructions to the Ephesian believers form a major part of the letter to the Ephesians, beginning at Eph 4:1 and extending to 6:20. The problem confronted by Paul as Apostle to the Gentiles was that many of his converts, coming from a pagan background and lifestyle, did not understand what was expected of them as followers of Jesus Christ. Some apparently continued to behave in ways characteristic of their pagan background, as seen in Eph 4:25-32.
(This would not have been the case with Jewish converts, who would at least have been familiar with God’s moral and ethical expectations based on the Old Testament, even if they had difficulty keeping the law.) However, it is important to note several things: (1) Paul firmly rejected the idea, represented by the so-called “Judaizers,” that for Gentiles conversion to Christianity was a two-step process, first becoming a full Jewish proselyte (including male circumcision) and second becoming a follower of Jesus Christ. Paul held that Gentiles could remain Gentiles and become Christians directly without becoming Jewish proselytes first (and was supported in this by the decision of the Jerusalem Council, Acts 15:1-29). (2) Paul argued that Gentile converts were expected to change their former pagan behavior when they became Christians (for example, Eph. 4:25-32), but he did not make this a precondition for conversion (see Eph 2:8-9). Paul’s exhortation is essentially “Live this way because you are a Christian,” not “Live this way so that you may become a Christian.” Thus most of the second half of the letter to the Ephesians is introduced by Eph 4:1: “Therefore I…exhort you to live in a manner worthy of the calling with which you were called.”
