And unto 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; I know your works, that you are neither cold nor hot: I would that you were cold or hot. So then because you are lukewarm, and neither cold nor hot, I will spew you out of my mouth. Because you say, I am rich, and increased with goods, and have need of nothing; and know not that you are wretched, and miserable, and poor, and blind, and naked: I counsel you to buy of me gold tried in the fire, that you may be rich; and white clothing, that you may be clothed, and that the shame of your nakedness does not appear; and anoint your eyes with eye salve, that you may see.

As many as I love, I rebuke and chasten: be zealous therefore, and repent. Behold, I stand at the door, and knock: if any man hears my voice, and opens the door, I will come in to him, and will eat with him, and he with me. To him that overcomes will I grant to sit with me in my throne, even as I also overcame, and sat down with my Father in his throne. He that has an ear, let him hear what the Spirit says unto the churches.
(Revelation 3:14-22)
