him who has an ear

"To the angel of the church in Laodicea write: These are the words of the Amen, the faithful and true witness, the ruler of God's creation. I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth. You say, 'I am rich; I have acquired wealth and do not need a thing.' But you do not realize that you are wretched, pitiful, poor, blind and naked. I counsel you to buy from me gold refined in the fire, so you can become rich; and white clothes to wear, so you can cover your shameful nakedness; and salve to put on your eyes, so you can see. Those whom I love I rebuke and discipline. So be earnest, and repent. Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with him, and he with me. To him who overcomes, I will give the right to sit with me on my throne, just as I overcame and sat down with my Father on his throne. He who has an ear, let him hear what the Spirit says to the churches."
