“I know your works, that you are neither cold or hot. I wish that you were cold or hot! So, because you are lukewarm, and neither hot nor cold, I am going to vomit you out of my mouth” (Revelation 3:15-16, HCSB).
While the church in Sardis was chastised for its dearth of spiritual vitality, the spiritual condition of the church in Laodicea was repugnant because it was lukewarm–neither cold nor hot.
