Martyn Lloyd-Jones’ sermon on Ephesians 5 takes a long time to make an important point: The church is not a morality club. The church does not call people to be good for the betterment of culture. We are called to live holy lives because it reflects our connection with our Holy God. We are not in the least concerned about living moral lives merely to help our children or to make our world a better place. Our goal is lofty. Our goal is to bring honor to God — the God we love and worship now, and the God we will serve and worship for all of eternity. The Christian life attempts to make real and substantive now what will be the reality of our life with God when we die.
Ephesians 5:3 and 5 repeats three classes of sins that must not even be named among those who believe: sexual immorality; all impurity; and coveteousness. Christians are called away from sexual immorality. Jesus famously called the people of his day, “this sinful and adulterous generation” (Matthew 12:39; 16:4; Mark 8:38). He called them this because they were, as in our day. Today our generation (every generation) is a sinful, an evil, and adulterous generation. But Christians are not to live this way. Christians are to be pure in sexual matters. We are to be careful about the relationships we enter into. We are to be honoring to others, remembering that a woman or a man with whom we have an affair has family, friends, and people who love them. Our sin will not remain private. Every adulterous act is brought out into the light. It is the nature of the case that no adultery, no uncleanness goes undiscovered. Certainly God sees all we do. We cannot hide our sin from him. But more than that, our faith in God is devastated by such actions. We hurt the lives of other people. We destroy or severely damage our Christian witness. We are not unlike the people of this age, doing the very things that will bring the wrath of God upon the sons and daughters of men.
Paul goes further: “such things as must not even be named among you, as is proper among holy ones” (Ephesians 5:3). An obedient church would not spend any time dealing with the adultery and uncleannesses of its people. They would not be matters that come up. The focus of the people is on God and his worship. Their energy is on pleasing and serving him, doing his will, training others, reaching the lost, caring for those in need. They don’t have time or need for adultery. Such things, for the obedient and the faithful, are not even named. In the faithful church adultery is not even discussed among them in a corrective or disciplinary way. Imagine a church where there was no adultery.
It is important to notice that Paul repeats the same language and warning twice in just three verses. In 5:3 and in 5:5 the same words are used. Beginning in 5:5 there is a stern warning: “Everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God. Verse 6. Let no one decieve you with empy words, for because of these things the wrath of God comes upon the sons of disobedience. Verse 7. Therefore do not become partners with them.” Paul repeats the warning about the three sins,”adultery, impurity (uncleanness), an covetousness” and the shows that these sins are not merely unseemly, but they are disqualifiers from entering the kingdom of Christ and of God.
In the age of grace we quickly apply the forgiveness of sins to every sin and to any sinner. The adulterer caught in adultery may come before a church board or pastor and confess their sin in order to be restored or to have their guilt assuaged. But does the pastor tell them that they cannot inherit the kingdom of Christ and God? Does the board of the church identify this sin as exclusionary and a mark of God’s ultimate judgment?
The church is made up of former adulterers and filthy and idolatrous people who have been saved by the grace of God. The church is filled with people who used to do these things, but who no longer do them. The excuse that the person is addicted to sex or that they couldn’t help themselves does not stand against the categorical condemnation of these sins. These sins are not part of the Christian’s life. They cannot be part of the Christian’s life. They must not be so alien to the Christian’s experience that there is no need to mention them in the fellowship of true Christian people.
Harshness of the condemnation of these triple sins.
In the day of cheap grace we find that any condemnation is unacceptable. We find that telling anyone that their sin puts them beyond the grace of God seems too harsh and we are hesitant to tell them that what they did excludes them from the kingdom of Christ and of God. But is this not what Paul says?
The Gospel of Christ is transformative. If it is not transformative — if peoples’ lives are not changed — it is not the gospel that is at work in people. If a person continues to sin (Romans 6:1) and depends on the grace of God to restore and to restore and to restore, they have not understood the grace of God. Paul erupts in Romans 6 with an invective, we could say he is swearing, cursing, better to say he is absolutely condemning those who say they should keep on sinning that grace might abound. He cannot stand the thought of those who would excuse their bad behavior because God is gracious. They have not understood nor do they know the transforming grace of God. “May it never be!”
But ask an adulterer if they are willing to stop it for their love of Jesus Christ — ask them if they are willing to stop that the purity of the Church may be protected. Ask the adulterer if they are willing to stop so that they might grow in faith and in faithfulness to God. If they are a Christian they will stop it. They will hate what they have done. They will see the damage they have caused. They will know that God’s honor, God’s law, God’s character were assaulted by their sin. They will break away from the adultery and they will find the grace of God sufficient, abundant, competent to change their lives and to free them from the sin that entrapped them.
“Because of these things (these three sins) the wrath of God comes upon the sons of disobedience” (Ephesians 5:6). How can a Christian continue to do what brings the wrath of God upon those who will spend eternity in Hell?
Redeeming our walk.
Ephesians 5:8, “You were darkness … now you are light. Walk as children of light.” How do children of light live their lives? “It is found in all that is good and right and true … and try to discern what is pleasing to the Lord.” The good and the right and the true are the things that we ought to be doing and focused on as we live our lives. Good. The things that mirror the nature and character of God. Right. The things that measure up to the moral character and the law of God. True. The things that are based on the existence of God and his involvement in every event of our lives. We form our choices based on the revelation of God’s Word and seek to make decisions not on human wisdom but on the wisdom of God’s Word. How different is this from the adulterer! He does what is bad, and wrong, and a lie. We begin to see how completely different the lives of Christian people must be. Good, Right, and True – Versus – Bad, Wrong, and Lying.
The instruction could not be clearer. The issue now becomes, “How will I live as a Christian?”
