1st Thess.4:13-18/ 13)But I would not have you to be ignorant, brethren, concerning them which are asleep (/physically dead/), that ye sorrow not, even as others which have no hope /Luke 24:5/.
14)For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him (/Resurection/).
15)For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. /prevent-Strong's # 5348- to be beforehand, precede-We cant precede them for they have already passed over!
16)For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: (7th trumpet)/when it comes to those who are born again they take part in the 1st resurection!
17)Then we which are alive and remain shall be caught up together with them in the clouds(/Large group/Heb.12:1), to meet the Lord in the air(spirit-air-Ruach): and so shall we (those who take part in one of the 2 resurections) ever be with the Lord.
18)Wherefore comfort one another with these words.
Note the symbolizim throughtout the Word always stays the same.
Cloud- Crowd (fig.)example:Heb.12:1
Air represents Spirit as I document over and over/
John 3:8
The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
(You can see the effects of the wind but not the wind. Just as you can see the Works (fruits) of the spirit but not the spirit. The Spirit realm is unseen to the physical this is why those who are taken to see certain heavenly things are taken in the spirit! This is why no Man has seen God.)
What do we describe as unseen?
Faith, Belief, Heart , Love, Ideologies, Mind (Intelect)/ the Holy spirirt being devine intelect. you will find this lines up with all mention of Spirit and the Holy Spirit within scriptures! Not to mention we use the Greek term for Spirit to say air in many cultures today- pneuma- pneumatic tires! (Hebrew- Ruach)
God is in control of who recieves what revelations. His children hear his Word and see the context of such!
