1 Thessalonians 4

13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. 14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 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. 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. 18 Wherefore comfort one another with these words.

Here's what I want to focus on out of this passage:

that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.

we which are alive and remain.......what do we know about the timing

2 Thes 2
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;

We know it will be a time of DECEPTION and APOSTACY, so what does this have to do with "we which are alive and remain unto the coming of the Lord?"

Some suggest that the words "alive and remain" have something to do with christians being killed in the tribulation, I counter that with the word of God which says at the time of the anti-christ being revealed, there will be few true believers left due to deception and apostacy. The REMAINING FEW (Matt7:14), who are still true to the Lord and His Word will be raptured in order to ESCAPE ALL (Luke 21:36) that's about to happen.
