When I used the word “lukewarm,” a couple entries ago, I thought of this passage from the Book of Revelation:
“And to the angel of the church at Laodicea write thus: A message to thee from the Truth, the faithful and unerring witness, the source from which God’s creation began: I know of thy doings, and find thee neither cold nor hot; cold or hot, I would thou wert one or the other. Being what thou art, lukewarm, neither cold nor hot, thou wilt make me vomit thee out of my mouth.”
