Rev. 3:1-6 – To the angel of the church in Sardis write: The One who has the seven spirits of God and the seven stars says: I know your works; you have a reputation for being alive, but you are dead. Be alert and strengthen what remains, which is about to die, for I have not found your works complete before My God. Remember therefore what you have received and heard; keep it, and repent. But if you are not alert, I will come like a thief, and you have no idea at what hour I will come against you. But you have a few people in Sardis who have not defiled their clothes, and they will walk with Me in white, because they are worthy. In the same way, the victor will be dressed in white clothes, and I will never erase his name from the book of life, but will acknowledge his name before My Father and before His angels. Anyone who has an ear should listen to what the Spirit says to the churches. (HCSB)
Sardis is located 30 miles southeast of Thyatira and is an important commercial city situated on a major east-west trade route. Key goods produced there include jewelry, dye and textiles. From a religious perspective, Sardis is a pagan city with a temple to Artemis, the ruins of which still remain. Archaeologists also have located the ruins of a small Christian church building next to the temple.
Sardis is said to be the chief city of Asia Minor in John’s day and perhaps the first city in that part of the world converted to the preaching of John. It also may have been the first city there to abandon Christianity and come to ruin. Christ’s stern message is not completely in vain, however, for we know of the second-century bishop Melito who distinguishes himself with piety and learning. Even so, the local church does not endure, nor does the city; only a village called Sart remains today among the ruins.
