Well Jesus will return personally. Acts 1:10-11, And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel, who also said, “Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.”
Many things prophesied have happened already. But more things of what were prophesied still come.
"Upon the earth distress of nations, with perplexity, the sea and the waves roaring, men's hearts failing them from fear and the expectation of those things which are coming on the earth" These are such things that are coming now, which many are just starting to see, with the climate change with warming and arctic ice more rapidly melting, the sea level rising, with some islands having sunk already, and more of severe storms.
Mystery Babylon must be considered, it has not fallen yet. What is shown for it in passages is indicating it is much greater than one city, that would never have as much attention, by merchants in the prophecy or by the scripture passages for the fall of it being such a great event. Not even that for a church or a religion would be. The characteristics shown of it correspond to what there is in the history of all great cities, it is characteristic of all civilization, starting from Babel. Yahweh was not promoting or endorsing civilization which humanity came up with, contrary to what Yahweh told for Adam and Eve for them and their descendants. Civilization is not godly, it is godless, God's people need to be called out from this Mystery Babylon.
