Revelation 3:18-20

18I counsel thee to buy of me gold refined by fire, that thou mayest become rich; and white garments, that thou mayest clothe thyself, and that the shame of thy nakedness be not made manifest; and eyesalve to anoint thine eyes, that thou mayest see.

19As many as I love, I reprove and chasten: be zealous therefore, and repent.

20Behold, I stand at the door and knock: if any man hear my voice and open the door, I will come in to him, and will sup with him, and he with me.
