“The seventh and final letter to the churches of ancient Asia Minor is to the church in the city of Laodicea. This last message is found in Revelation 3:14-22. Laodicea was a wealthy, industrious city in the province of Phrygia in the Lycos Valley.
The message is from the Lord Jesus Christ via an angel or messenger (likely a reference to the church’s pastor): “To the angel of the church in Laodicea write . . .” (Revelation 3:14). This was not simply John’s message to those in Laodicea; it was a message from the Lord. Jesus identifies Himself thus: “The Amen, the faithful and true witness, the ruler of God’s creation.” These titles emphasize the Lord’s faithfulness, sovereignty, and power to bring all things to their proper completion (the “Amen”).
In contrast to the other six churches, the Laodicean church has nothing to commend it. Jesus begins the message with condemnation: “I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth. You say, ‘I am rich; I have acquired wealth and do not need a thing.’ But you do not realize that you are wretched, pitiful, poor, blind and naked” (Revelation 3:15-17). Jesus emphasizes their “lukewarm,” apathetic nature three times. As a result of their ambivalence to spiritual things, Jesus would have nothing to do with them. He would “spit them out,” as the people of Laodicea would spit out the tepid water that flowed from the underground aqueducts to their city. With their apathy came a spiritual blindness; they claimed to be rich, blessed, and self-sufficient. Perhaps they were rich in material things. But, spiritually, the Laodiceans were in a wretched, pitiful condition, made all the worse in that they could not see their need. This was a church filled with self-deceived hypocrites…
…In summary, the church at Laodicea had become apathetic in their love for Christ. They were allowing “the deceitfulness of wealth and the desires for other things [to] come in and choke the word, making it unfruitful” (Mark 4:19). Christ called them to repent and live zealously for Him, to “choose for yourselves this day whom you will serve” (Joshua 24:15). The Lord Jesus issues the same call to those who say they follow Him today. ” 1
