The lukewarm church - Revelation 3:14-22

Despite all of their prosperity, the city of Laodicea lacked a quality water supply. As a result, they relied on a combination of nearby sources that produced lukewarm water which was known to be repugnant. Christ uses this to help paint a picture of the local church in this community. They were neither providing refreshment for the spiritually thirsty, not healing the spiritually sick. As a result, Jesus threatens to cast them from His mouth.
