Revelation 3

16 So because you are lukewarm (spiritually useless), and neither hot nor cold, I will vomit you out of My mouth [rejecting you with disgust]. 17 Because you say, "I am rich, and have prospered and grown wealthy, and have need of nothing," and you do not know that you are wretched and miserable and poor and blind and naked [without hope and in great need], [Hos 12:8]
