Its not the Second Coming in reality as Jesus has come back to earth many times, John 20 proves he came back to allow Thomas to TOUCH HIM, after telling Mary to NOT TOUCH HIM, because he had not yet ascended to the Father to offer the Sacrifice, and her SIN FLESH would have defiled the offering, seeing as no SIN FLESH can enter heaven.
The Second Coming really means the Second Advent, I know that, so when I say Second Coming, I am just going with the flow, but I mean of course the Second Advent. The First Advent was a Suffering Servant The Second Advent is as a Conquering King.
So the Second Coming is Jesus returning to rule on this earth via his 1000 year reign. He brings us {the Church} back with him just as Rev. 19 shows after we marry the Lamb. Its right there in writing. We see the Church in Rev. 4 and 5 BEFORE the Seals are opened.
Rev. 8, starts the Day of the lord, it lasts through 3.5 years of Wrath AND 1000 years of his Glorious reign.
