Jesus says Laodicea is neither cold nor hot, but lukewarm Revelation 3:15–16. He connects this to their claim of being rich and needing nothing while not realizing their true condition Revelation 3:17.
In Revelation 3:14–17, the speaker addresses the Laodicean church through a messenger and introduces himself with titles that stress reliability and authority. He evaluates their “works” and finds them neither “cold” nor “hot,” calling them “lukewarm,” a condition he rejects strongly. These verses belong to the set of short messages to seven churches in Revelation 2–3.
The passage presents Jesus as a fully reliable judge of the Laodicean church’s condition. His opening titles (“the Amen,” “the Faithful and True Witness,” and “the Head of God’s creation”) frame what follows as trustworthy assessment, not rumor or guesswork (Revelation 3:14).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Revelation 3:15-16, then read the surrounding section so the answer stays connected to the passage's flow.
15"I know your works, that you are neither cold nor hot. I wish you were cold or hot.
16So, because you are lukewarm, and neither hot nor cold, I will vomit you out of my mouth.
