We have a soul which is not bound to our current 4D coordinate system but is interfacing with it to ride along in spacetime with a physical body. Chuck Missler used to say that our body is hardware but our soul is software, like what is imprinted on a floppy disc, the disc being the hardware of body and the data being the software soul or behavior mechanism.
This was an interesting analogy but not quite correct. The body is more akin to the machine that reads the data imprinted on the disc, the disc being the soul and the body the reader of the data on the disc. Missler was correct though in saying if I look at you, the physical you, I see but do not see the real you, the behavior mechanism that is your soul.
This causes our soul to have sensory limitations, but the soul is real and has space and time reality. The spirit is likewise interfacing with the soul. Unless one is born again/born from above/made alive in the spirit the natural spirit state of those descended from Adam is a state of deadness toward righteousness.
When one is born again, as Jesus told Nicodemus needs be to see the Kingdom of God, it is GOD Who separates the soul and spirit (the Word of God is sharper than any two-edged sword, able to separate soul and spirit). Thereafter it is God's Seed that abides in the newborn spirit, while the dying body with soul knowing only how to sin continues existing.
Regarding the Rapture ('harpadzo' in the Greek) or Departure --as harpadzo was translated in the first English versions from the Greek-- The Presence of God's 'seed' (read Holy Spirit earnest of our inheritance) is the creation point/moment of God creating a new body and behavior mechanism for each born again member of the Body of Christ ('body of' as in the collective student body of a particular college, for instance).
God does miracles; Angels use technology involving higher coordinate systems, and there are bad Angels and Good Angels. The Departure snatching away is a great miraculous moment, a moment of God creating new bodies for all in Christ, past or present.
There is physical reality we cannot now sense, as one more variable of space is included there or one more variable of time is in that 'other coordinate system'. We can be assured of this 'other coordinate reality' if We believe the Bible is True, and the Book of Daniel was truth (Jesus did refer to that Book). In the fifth chapter of Daniel we read of an interesting surreal event, where a hand appeared from some other where/when and wrote upon the wall of palace party central, Babylon. The hand was part of a real, physical being existing in a different where/when that the palace, but was reaching into the coordinate system of the palace to write upon the wall.
That is a complicated way to look at it and more complicated to explain to an average interested person.
i have a son who studied both Hebrew and Greek in college at the same time.. he has a brain that records.. he also knows the Bible.. he knows the meaning of what was said and translated into English. he is also a lawyer.
i have another son.. equally as astute and as bright.. but music instead of Bible.. tho he knows the Bible and can tell anyone what it says.. but he says there are inconsistencies throughout.
no amount of explaining convinced son #2 of the Bible absolute truth.. “it was written by man”.
Then comes sickness in #2 son and one night he had a vision. Jesus visited my son.
I wont go into all he saw.. but it was a miracle and the Holy Spirit did in 5 min what all the talk did not do. #2 son became a thankful believer..
Simple... one glimpse...
