He used the word "regenerate" and I was addressing that.
You are wrongly going to a text which was written to Christians to do so. Rev 3 is not an invitaion for salvation. It is the correction of a "lukewarm" church. Read it for yourself. It has nothing to do with unregenerate men being regenerated.
To the Church in Laodicea
14“And to the angel of the church in Laodicea write: ‘The words of the Amen, the faithful and true witness, the beginning of God’s creation.
15“‘I know your works: you are neither cold nor hot. Would that you were either cold or hot! 16So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. 17For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked. 18I counsel you to buy from me gold refined by fire, so that you may be rich, and white garments so that you may clothe yourself and the shame of your nakedness may not be seen, and salve to anoint your eyes, so that you may see. 19Those whom I love, I reprove and discipline, so be zealous and repent.20Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me.
