Revelation 14:14-20 is the cloud-coming that "every eye would see." This is significant, for St. John is not describing the coming of Christ as some visual spectacular with cumulus clouds in the skies overhead, but as the coming of Yahweh himself, making Christ equal with the Father. Christ's return was to be precisely in the manner and tradition of Yahweh's Old-Testament-era comings. We have countless examples of the Father coming in His great glory during the Old Testamental period
(be sure to note the graphic, physical descriptions and explicit "visual" connotations of Yahweh's comings, noticing how the same language is used to describe the Coming of Christ):
[On Jehovah's coming at Mt. Sinai] Jehovah came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them (Deut 33:2; cf. Neh 9:13-15; Hab 3:3-16)
[On Yahweh's coming to Egypt -- early 700s BC] Behold, Yahweh rides on a swift cloud, and comes to Egypt: and the idols of Egypt shall tremble at his presence; and the heart of Egypt shall melt in the midst of it. I will stir up the Egyptians against the Egyptians (Isaiah 19:1-2)
[On Yahweh's coming during the Maccabean Period] For I have bent Judah for me, I have filled the bow with Ephraim; and I will stir up your sons, Zion, against your sons, Greece, and will make you as the sword of a mighty man. Yahweh shall be seen over them, and his arrow shall go forth as the lightning; and the Lord Yahweh will blow the trumpet, and will go with whirlwinds of the south. Yahweh of Hosts will defend them; and they shall devour, and shall tread down the sling-stones; and they shall drink, and make a noise as through wine; and they shall be filled like bowls, like the corners of the altar. Yahweh their God will save them in that day (Zechariah 9:13-16)
[On Yahweh's coming to Israel for Babylonian Exile - 6th Century BC] Therefore thus says the Lord Yahweh: Because you are turbulent more than the nations that are round about you, and have not walked in my statutes, neither have kept my ordinances, neither have done after the ordinances of the nations that are round about you; therefore thus says the Lord Yahweh: Behold, I, even I, am against you; and I will execute judgments in the midst of you before the eyes of the nations. I will do in you that which I have not done, and whereunto I will not do any more the like, because of all your abominations (Ez 5:7-9)
[On Yahweh's coming to Israel for Babylonian Exile - 6th Century BC] As I live, says the Lord Yahweh, surely with a mighty hand, and with an outstretched arm, and with wrath poured out, will I be king over you: and I will bring you out from the peoples, and will gather you out of the countries in which you are scattered, with a mighty hand, and with an outstretched arm, and with wrath poured out; and I will bring you into the wilderness of the peoples, and there will I enter into judgment with you face to face...Hear the word of Yahweh: Thus says the Lord Yahweh, Behold, I will kindle a fire in you, and it shall devour every green tree in you, and every dry tree: the flaming flame shall not be quenched, and all faces from the south to the north shall be burnt thereby. All flesh shall see that I, Yahweh, have kindled it...Thus says Yahweh: Behold, I am against you, and will draw forth my sword out of its sheath, and will cut off from you the righteous and the wicked. Seeing then that I will cut off from you the righteous and the wicked, therefore shall my sword go forth out of its sheath against all flesh from the south to the north: and all flesh shall know that I, Yahweh, have drawn forth my sword out of its sheath (Ez 20:33-35,47-48; 21:3-5) Jehovah hath made bare His holy arm before the eyes of all nations (Isa 52:10)
These are just a few examples of the Father's Old-Testament comings, but there are many others: Yahweh came down and shot arrows at Saul and his armies, shaking the earth's foundations and the heavens at that time (2 Sam 22:8-16); Yahweh is depicted as having destroyed the universe when he judged Israel through Babylon (Jer 4:22-30), and did so again when he judged Egypt by Babylon's King Nebuchadnezzar (Ez 32:1-16). The Father entered into judgments with Egypt and Assyria in a spectacular coming in Isaiah 31. Habakkuk's depiction of Jehovah's coming at Mt. Sinai is nothing less than apocalyptic (Hab 3:3-16).
Were any of these OT comings visual, physical/literal appearances of Yahweh as the prophets describe in metaphorical prophetic language? Of course not (Jn 1:18; 1 Jn 4:12)--the Hebrews understood that no human could ever see Yahweh and live (Exodus 33:20).
Importantly, these comings of the Father form the entire backdrop for the doctrine of the "coming" of Christ, for it was in this manner of the Father's glory that Christ said he would come (Matt 16:27-28; Lk. 9:26; Matt 24:33-34).
