There are many other people today in various situations who say: “There is no hope for me. There is no use for me to try.” Those Ephesians might have talked the same way. They had just as much reason to do so as any one else. Probably some of them did talk like that and were lost; who can tell? There were a great many, however, who turned from idols to serve the true and living God, received Christ into their hearts, and found the power of salvation in the gospel. They found power in the blood of Christ to cleanse them from their impurities, and not only so, but also to raise them so far from the mire of sin and wickedness abounding around them as to keep them faithful in Christ Jesus while still dwelling in Ephesus. It is not so much a change of environment that people need as a change of heart and of character. Diamonds are often found embedded in volcanic mud; mud surrounds them on every side, and yet they have lain there for centuries and are still diamonds. What is the secret of it? Why have they not become contaminated? It is because the mud never entered the diamond; and that was the reason that the Ephesian saints could be faithful and still live in Ephesus. They were left amidst the foul mud of corruption, but the mud was taken out of them, and the grace of Christ kept it from getting back in again. We can not get away from the mud and defilement of sin in this world. Sin will ever be all about us. Its stench will be in our nostrils from day to day. Our eyes will be offended by it, and our ears will be shocked. But so long as we keep it all on the outside, we can be saints and faithful in Christ Jesus. We are told that one of the chief things for us to do is to keep ourselves “unspotted from the world.” Phil. 2: 15 says, “That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world.” Again Paul says, “Neither be partakers of other men’s sins: keep thyself pure” (1 Tim. 5: 22). We are not only to keep free from committing any sins of our own, but also to avoid partaking of the sins of others. That is very important. Now, we are, as it were, in Ephesus. There is sin abounding all about us. God wants us so to abhor the sins of others that we shall not follow them, nor find pleasure in those who do sinful things. There are two ways in which we can partake of other people’s sins. One way is to approve of their evil works. It may be that we ourselves would not do those things, but if we approve of some one else’s doing them, it is just about as bad.
