If the dead are not caught up... who is the "them" here:
1 Thessalonians 4:16-17King James Version (KJV)
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:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
I already answered this question. The living are lifted up in order to meet "them" which are the resurrected saints.
1Th 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
The dead come with Christ. The dead are in heaven when they are resurrected. That's why Paul does not include the dead as part of the Harpazo.
Not only that but the scripture, here, states that they will "rise".
Yes but one must check the Greek definition to understand what the word means:
G450
ἀνίστημι
anistēmi
an-is'-tay-mee
From G303 and G2476; to stand up (literally or figuratively, transitively or intransitively): - arise, lift up, raise up (again), rise (again), stand up (-right).
Literally it means to stand up, figuratively it means to be resurrected from the dead.
Rapture has a different meaning:
G726
ἁρπάζω
harpazō
har-pad'-zo
From a derivative of G138; to seize (in various applications): - catch (away, up), pluck, pull, take (by force).
To be physically seized or caught upwards is what this word means.
When the dead "rise" it means they are resurrected not that they rise up into the air.
When the living are "caught up" they are lifted into the air physically.
This is why studying the bible and the original language is required to be able to understand any English translation.
