Knock

18 I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eye salve, that thou mayest see.

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

20 Behold, 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.

21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.

22 He that hath an ear, let him hear what the Spirit saith unto the churches…Revelation 3:18-22 (KJV)
