Revelation 3:14-16

14“And to the angel of the church of the Laodiceans write, ‘These things says the Amen, the Faithful and True Witness, the Beginning of the creation of God:

15“I know your works, that you are neither cold nor hot. I could wish you were cold or hot.

16So then, because you are lukewarm, and neither cold nor hot, I will vomit you out of My mouth.
