The water of Laodicea, site of one of the seven churches mentioned in the book of Revelation, came from hot springs immediately south of the city. By the time the water reached Laodicea it was lukewarm. Jesus described the church as being like the water supply of the city.
“I know your works: you are neither cold nor hot. Would that you were either cold or hot! So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth.” (Revelation 3:15-16 ESV)
Laodicea was one of three cities of the Lycus River Valley in Asia Minor (Colossians 2:1; 4:15-16). Today this area is in Turkey. Toward the end of the first century the book of Revelation was sent to several churches of Asia (Revelation 1:11).
This photo shows part of the water distribution tower at ancient Laodicea. Mount Cadmus, location of Laodicea, is seen in the distance.

Ruins of the ancient water distribution system at Laodicea. Mount Cadmus, the location of Colossae, is visible in the distance. Photo by Ferrell Jenkins.
Notice in the previous photo to the right of the ruins you will see several people gathered. They are looking at the calcified clay pipes that once distributed water to the residences of Laodicea. When the water left the spring it was warm, but by the time it arrived at Laodicea it was lukewarm.
How here is our favorite foto for today.

This picture shows one of the broken clay pipes in the water distribution system, now calcified. But notice the little plants growing in the pipe. Photo by Ferrell Jenkins.
A florist could hardly do better. This pipe apparently became so clogged that dirt could settle in it and provide a bed for these little plants.
Hi Ferrell,
One of our daughters and her husband would like to travel to the holy lands, and maybe Petra. Are you still leading tours? If so, when is your next trip to Israel planned and do you have space?
If not, is there a tour company you can recommend?
Thank you for your help.
Sincerely,
Kathy George
