Hi...I'm Gary - I was going to read all the previous posts on this subject but then I realized there were over 100 pages, so what I would like to say might have already been said at some point.
Although we don't know the day nor the hour there is a sequence of events, in the sense that one thing has to happen before another thing happens.
So when it says in 1 Thess. 4:16 that '....For the Lord himself shall descend from heaven with a shout...and with the trump of God; and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds...."
So looking closely at this we can see that there is an event that must happen before we are caught up or raptured. So it would be wrong to say 'the rapture can happen at any time, there is nothing that has to happen first." because clearly the dead in Christ must rise first before the living are caught up.
So what does it mean that the dead in Christ must rise first? For them to rise, or be 'caught up' first, what does that mean? It means before they can rise or be raptured, there must be a resurrection from the dead.
So the living saints of course will not need to be resurrected before they rise, because they are still alive, but for the dead in Christ to rise, they must first be physically resurrected.
Paul says '...we shall not all sleep, (die) but we shall all (both dead and living) be changed, in a moment, in a twinkling of an eye, at the Last Trump.
There are five things to note in the mystery Paul was revealing to us.
1) We shall not all sleep (There will be some believers that will be alive when this happens)
2) We shall all be changed (All the dead believers and the living believers will be changed)
3) In a moment (All believers, dead and alive will be changed (get glorified bodies) at the same time, in a moment)
4) In the twinkling of an eye (Making it clear that the time involved for all believers to receive their glorified bodies does not happen over an extended period of time, but in the twinkling of an eye)
5) At the last trump (making it known these events will not take place until the last trumpet sounds)
Seeing the resurrection of the dead in Christ must take place before the rapture, we know there can be no rapture before the resurrection. Its not that we know the day nor the hour, but we know that one specific event (the resurrection) must take place before the rapture (catching away) can occur.
So when does the scripture say the believers will be resurrected? Lets look at 4 verses in John 6 to see not only when this resurrection will happen, but who will be included in this resurrection.
John 6:39 -"And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day."
1) John 6:40 "And this is the will of him that sent me, that every one which seeth the Son, and believeth on him may have everlasting life, and I will raise him up at the last day.
2) John 6:44 -"No man can come to me, except the Father which hath sent me draw him; and I will raise him up at the last day."
3) John 6:54 -"Whoso eats my flesh and drinks my blood, hath eternal life; and I will raise him up at the last day."
The first reference says that all whom God has given to Christ he will raise them up (or resurrect) them at the last day.
So lets look seriously at the first reference....it says ALL those who God has given to Christ will be raised at the last day. Remember Paul used the same words when he said we shall ALL be changed in a moment. So ALL does not mean PART of the believers will be resurrected at one time and then the other PART resurrected at the last day, it means ALL those who God gave to Christ will be resurrected in a moment, in a twinkle of an eye, at the last trump.
So the thought that nothing has to happen before the rapture, or it could happen at any time is wrong...there must FIRST be a resurrection of the saints, and if that resurrection does not happen until the last day, then it would be impossible to have a rapture before the last day.
