Revelation 3:14-16

14And unto the angel of the Assembly of the Laodiceans write; These things saith the Amen, the faithful and true witness, the head of the creation of God; 15I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. 16So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.
