No but I'm thinking of drafting Jonathan Edwards into the High Council of the Order of the Eternal Exclamation Point with Asterik™ posthumously. He deserves a medal for his clear thinking on Revelation 3:20.
Too bad he didn't know anything about context. This is not a salvation scripture. It is written to the church at Laodicea, not to heathens:
`And to the messenger of the assembly of the Laodiceans write: These things saith the Amen, the witness--the faithful and true--the chief of the creation of God; I have known thy works, that neither cold art thou nor hot; I would thou wert cold or hot. So--because thou art lukewarm, and neither cold nor hot, I am about to vomit thee out of my mouth; because thou sayest--I am rich, and have grown rich, and have need of nothing, and hast not known that thou art the wretched, and miserable, and poor, and blind, and naked, I counsel thee to buy from me gold fired by fire, that thou mayest be rich, and white garments that thou mayest be arrayed, and the shame of thy nakedness may not be manifest, and with eye-salve anoint thine eyes, that thou mayest see. `As many as I love, I do convict and chasten; be zealous, then, and reform; lo, I have stood at the door, and I knock; if any one may hear my voice, and may open the door, I will come in unto him, and will sup with him, and he with me. He who is overcoming--I will give to him to sit with me in my throne, as I also did overcome and did sit down with my Father in His throne. He who is having an ear--let him hear what the Spirit saith to the assemblies.' (Rev 3:14-22)Young's Literal Translation
These people are already saved. Jesus says "Whom I love, I chasten," This is a chastening, in this message to the church. God deals with His own differently than He deals with the heathen. One of His Own is treated as a son, but He does not treat the heathen so. Of course you will say, "But Jesus loves everybody". Still doesn't change the fact, the cold hard fact, that this letter was written to a church, not to unsaved people. By extension, it is written to all churches. The condition of every church can be found in the messages to the churches in Revelation. Every church on the face of the earth today falls into one of those categories and descriptions.
Rev 3:20 is written to Christians, not to the unsaved.
