16:13-18 A Christian is always in danger, therefore should ever be on the watch. He should be fixed in the faith of the gospel, and never desert or give it up. By this faith alone he will be able to keep his ground in an hour of temptation. Christians should be careful that charity not only reigns in their hearts, but shines in their lives. There is a great difference between Christian firmness and feverish warmth and transport. The apostle gave particular directions as to some who served the cause of Christ among them. Those who serve the saints, those who desire the honour of the churches, and to remove reproaches from them, are to be thought much of, and loved. They should willingly acknowledge the worth of such, and all who laboured with or helped the apostle.
