Paul refers several times to the Christians at Laodicea in his letter to the Colossians. He expresses concern for believers at Colossae and Laodicea and instructs that his letter be read in the Laodicean church.
Revelation 3:14-22 contains the best-known biblical passage concerning Laodicea. The church is rebuked for being "neither cold nor hot" and for believing itself rich and self-sufficient while failing to recognize its spiritual poverty.
The message uses imagery involving wealth, clothing, sight, and lukewarm water that would have been especially vivid within the prosperous urban environment of Roman Asia.
