FROST:
So Christ's "coming quickly" was what I was saying then. He did not
actually return, but he worked out all the circumstances. He caused the earthquakes, plagues, suffering, bizarre heavenly events all from his place at the right hand of the Father. His "returning" was actually the promises being unfolded to them while He remained glorified in Heaven.
GW:
The coming/return of Christ that happened with those churches of Asia Minor is the promised second coming/return of Christ as it was taught all through the NT. Let's be very clear that Jesus links them for us--the coming of Christ to the churches of Asia Minor was the same coming of Christ promised by the apostles and Jesus all throughout the New Testament letters.

CHRIST TO PERGAMUM:
"you also have some who in the same way hold the teaching of the Nicolaitans. Therefore repent; or else I am coming to you quickly and I will make war against them WITH THE SWORD OF MY MOUTH"
--to this--
And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war...And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean. And OUT OF HIS MOUTH GOETH A SHARP SWORD, that with it he should smite the nations...And the remnant were slain with the sword of him that sat upon the horse, which SWORD PROCEEDED OUT OF HIS MOUTH (Rev 19:11,14-15,21)

CHRIST TO THYATIRA:
"you tolerate the woman Jezebel, who calls herself a prophetess, and she teaches and leads My bond-servants astray so that they commit acts of immorality and eat things sacrificed to idols...I will throw her on a bed of sickness, and those who commit adultery with her into great tribulation, unless they repent of her deeds. And I will kill her children with pestilence, and all the churches will know that I am He who searches the minds and hearts and I will give to each one of you according to your works."
--to these--
"For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works." (Matthew 16:27)
"thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God, Who will render to every man according to his works" (Romans 2:5-6)
--next, compare this--
CHRIST TO SARDIS:
"Wake up, and strengthen the things that remain, which were about to die; for I have not found your deeds completed in the sight of My God. So remember what you have received and heard; and keep it, and repent. Therefore if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you."
--to these--
"Watch therefore: for ye know not what hour your Lord doth come. But know this, that if the goodman of the house had known in what watch THE THIEF WOULD COME, he would have watched" (Matthew 24:42-43)
"you yourselves know perfectly that the day of the Lord so cometh AS A THIEF in the night. For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. But ye, brethren, are not in darkness, that that day should overtake you AS A THIEF." (1 Thess 5:2-4)
--and compare this--
CHRIST TO THE LAODICEANS:
"Behold, I stand at the door and knock"
--to these--
when ye shall see all these things, know that he is near, even at the door (Matthew 24:33)
James 5:8-9
for the coming of the Lord is near...behold, the judge standeth before the door. (James 5:8-9)
--
In sum, the coming of Christ to the churches of Asia Minor was the same coming of Christ promised by the apostles and Jesus all throughout the New Testament letters.
