This is off topic but I have already shared I am not a pre-trib rapture believer.
Are you equating this discussion as the rapture being associated with the 7 Churches?
In reading Rev 1...I read that the 7 stars are the 7 angels assigned to the 7 churches, and the 7 candlesticks are the 7 churches...
The guide I use is that often the top part of a vision says something about the 3rd heaven, the middle parts the 2nd and lst heavens, and at times the bottom the earthly.
A vision can portray the same thing in two ways too as we see with the candlesticks and the stars. What they have in common is that both are sources of light. The stars in the hand show me that "Jesus' hand" is operating at a lower level than his head. I'd would guess those stars are in the firmament between the "upper waters" and "lower waters."
The candlesticks would be another way of showing the same thing but from a different perspective. They are not "rooted" in the earth but stand on it; and their light is coming from above.
Now I am in Chapter 11...the 2 witnesses....they are called the 2 olive trees and the 2 lampstands that stand before the God of the earth....in cross referencing I am taken to Zechariah...who is shown two olive trees standing on each side of the golden candlestick who receive the golden oil that is poured out...the 2 anointed ones.
These could be said to be two more stars but it doesn't say that. They are candlesticks like the seven spirits -- I read it the same way. We also are told that they are trees -- with roots in the earth. They relate to the earth in a way the seven spirits do not.
Not only are they burning oil to make light, they are growing olives to make more oil. The glory of God is already ever present but concealed. When a saint is doing the business of Heaven properly, he is collecting this unmanifested concealed glory in the earth with his roots. It is collected in the olives which are then pressed -- one taken, one left behind so to speak -- the heavenly is separated from the earthly.
Then if the person has "the spark" of fire, his lamp is lit -- and the hidden glory of God can be revealed.
If we lack enough oil ourselves, we may need to "buy" it. We can make it ourselves; but we can also get it from others.
Matthew 25:7 Then all those virgins arose, and trimmed their lamps.
8 And the foolish said unto the wise, Give us of your oil; for our lamps are gone out.
9 But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves.
10 And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
11 Afterward came also the other virgins, saying, Lord, Lord, open to us.
12 But he answered and said, Verily I say unto you, I know you not.
I would say the two witnesses then represent two sources of this oil as well as being lampstands themselves; and they are connected to the seven other lampstands.
