'I know your works; you are neither cold nor hot. I wish that you were either cold or hot. So, because you are lukewarm, and neither cold nor hot, I am about to spit you out of my mouth. For you say "I am rich, I have prospered, and I need nothing." You do not realize that you are wretched, pitiable, poor, blind and naked. Therefore I counsel you to buy from me gold refined by fire so that you may be rich; and white robes to clothe you and to keep the shame of your nakedness from being seen; and salve to anoint your eyes so that you may see. I reprove and discipline those whom I love. Be earnest, therefore, and repent. Listen ! I am standing at the door, knocking; if you hear my voice and open the door, I will come in to you and eat with you, and you with me. (Revelation 3 : 15 - 20)
