I agree with the bolded part.
All of the book of Revelation is future. The bible plainly says Enoch died. It plainly says no man has ascended to heaven except Christ.
I grant this, they may have been taken to Abraham's bossom. But now, Heaven is open.
Mat 27:51-53 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; (52) And the graves were opened; and many bodies of the saints which slept arose, (53) And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
These OT saints are in heaven. He pulled them out and they are gone.
And not all the book of Rev is future. Rev 12 starts out with an event that has already happened. WHen John sees the throne room in Rev 4, when he is given the revelation, chapter
4 is a past event, but it is given so you would understand and see what is going on and takes
you into future events. John sees the elders, which had already gone and BEFORE Jesus
went up. Jesus stayed on the earth 40 more days to explain things, but those elders
John sees in Rev 4 are those in Mat 27:51-53. There isn't any reference to Jesus, the Christ
or the Lamb in chapter 4. In Chapter 5, the Lamb appears. The 40 days are over and Jesus
goes up. These elders are brought up to speed about the scriptures and Him, then you see
them worshipping the Lamb. By the time John sees this, its a past event. The future starts
when the Lamb takes the scroll.
Then later, John sees a multitude of people from nations and languages. You go from 24 elders
to a multitude. That's gentiles, or the church, which is mostly gentiles. Before that scene
John sees the 144,000, which is the first fruits. The times of the gentiles is over and those
144000 are the first to see the truth.
So, no more gentiles are going. Those 144000 don't need to be preached to, because God
seals them. The spiritual blindness is taken away and they see the truth about Jesus.
From here on out, its all about the Jews. People think the Gentile church is going through
this, but their job and time is over. Everything is centered around Jews and Israel.
