I can’t help but think of this song when I read vs.18. We begin Paul’s letter to the church in Ephesus. It is thought to have been written in 62 while Paul was in prison in Rome. This is another church that Paul founded. If you go back to Acts 18:19-21 you see that Paul briefly visited Ephesus and this work was carried on by Apollo and Aquila and Priscilla. He then later spent three years in Ephesus. Needless to say it is a church that he knows well and that he loves. Unlike the churches in Galatia, this church is not leaving the faith. It is one in which Paul can rely.
If you look at vs.15 and 16 you will see the love that Paul has for this church is revealed in these words: “I have heard of your faith in the Lord Jesus and your love[e] toward all the saints, and for this reason I do not cease to give thanks for you as I remember you in my prayers.”
