First Love - Lost and Found

Did you know there are two New Testament letters to the church in Ephesus? The first was authored by the Apostle Paul in ca 62 AD. The second by the Lord Jesus (through the Apostle John) about 30 years later. What do you suppose can happen to a good church as the first generation ages and the next generation comes on the scene? The church in Ephesus appears to have been a pretty good church, but Jesus' letter indicates that sometimes good might not be good enough!
