I am a firm believer that all those "in Christ" are getting raptured, regardless if they are actively watching or not.

Paul, in providing comforting words to believers within I and II Thess, does not qualify it.  We are all included.  In a word, "Grace".

He does teach that the dead in Christ rise first then we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air.  This is actually what I mean when I use the word "split".

Prior, I had the assumption that "together" can only mean in that same split second of time.  That may end up being the case but I am now wondering if it will, instead, have maybe up to ten days between the rapture of the dead in Christ compared to the rature of those who are alive and remain.

Having said that, I am still thinking that we will all, the dead in Christ and those who are alive and remain, experience a change of our bodies into immortality together.

This is why I am considering this possibility of a small number of days being between both aspects:

What got me to questioning my presupposition that both get raptured basically at the same time, was something Paul writes in Phil. 3 : 11, "in order that I may attain to the resurrection of the dead."  He seemed to desire this so much while he was alive he said such things as "forgetting what lies behind and pressing forward to what lies ahead", desiring to "attain to the prize of the upward call of God in Christ Jesus."

Why would he want to attain to the resurrection of the dead while he was still alive?  Unless . . .

The focus of Phil. 3 is the utter worthiness of knowing Jesus, and that all else is nothing compared to this.  It seems to me that all "in Christ", who have already physically died, know this truth at this point in time.  Right now in heavenly places, they know the absolute truth that it is all because of Jesus, with their hearts consumed with an experience of His love now, and longing to pour out their love to Him in return at any opportunity they get.

What if that is what it actually means to be "dead in Christ", that our hearts want nothing the world has to offer as a substitute for knowing intimacy with Jesus?  that we have come to understand, and have accepted, our crucifixion together with Christ and our aliveness only to Him who is our life?  Due to our hearts' longing for Jesus, we exist down here as "dead to the world" people because we have come to know that our life is indeed hid with Christ in God.

And what if, like Paul expressed while he was still alive on earth, that having our focus only on love for Jesus, that we might go up in the very moment that the other "dead" are raised (perhaps on Jesus' ascension day?).  Paul did not presume this for himself but seemed to make it his only goal to press on towards as expressed in Phil. 3.

What if this will be the bride within the body of believers, with the rest being harvested (harpatzo-ed) perhaps ten days later on pentecost?

What I am speculating is that I think we will all be taken up in one "event", but the event might take place over a few days period of time.

Those who are alive, and yet who "remain" on earth after the dead in Christ are raised first, though also having been transformed into their new bodies, will be witnesses to bring in the last (the corner gleanings?) group of others as the final part of the barley crop is then harvested.

This is a theory.  But I had wondered in the past, "Why did Paul want to attain to the resurrection of the dead, as a 'then alive' believer if the rapture of the dead and living was to happen virtually simultaneously anyway?"  And, "What difference does it make to want to be raptured with that the dead in Christ anyway?  Don't we all basically  receive the same thing?"

Also, I had wondered, when Paul elsewhere referred to 'the living at the time of the rapture', that he described them as being those "who are alive and remain" instead of only referring to them as "alive"? Why add the word "remain"?  Remain for or after what?

Unless the rapture of the "dead to only Christ" precedes the rature of those who are alive (to the world?) by a short window of time within the one main event of the harvest being gathered together to meet Christ in the air, and the fulness of the Gentiles is brought in.

I am not certain of the above.  I do know that Jesus is coming soon, and that He alone is worthy of our full hearts' focus and devotion,

Sincerely,  Douglas Henney.
