Absent or Present Bodies

At a couple of funerals recently  I have heard a reference by David Dahms to a concept that was new to me so I throw it out for examination.  He mentioned that Maxine DeVilbiss was already in her new body with Jesus.  When asked about this he quoted the familiar verse in II Cor 5:6-9 "So, always be cheerful!  As long as we are in these bodies, we are away from the Lorde.  But we live by faith, not by what we see.  We should be cheerful, because we would rather leave these bodies and be at home with the Lord.  But whether we are at home with the Lord or away from Him, we still try our best to please Him."

The context that begins chapter 5 is to the point,  "Our bodies are like tents that we live in here on earth.  But when these tents are destroyed, we know that God will give each of us a place to live.  These homes will not be buildings that someone has made, but they are in heaven and will last forever.  While we are here on earth, we sigh because we want to live in that heavenly home.  We want to put it on like clothes and not be naked.  These tents we now live in are like a heavy burden, and we groan.  But we don't do this just because we want to leave these bodies that will die.  It is because we want to change them for bodies that will never die.  God is the one who makes all of this possible."

This certainly makes the case for the new body and seems to be talking as much about being in our new bodies  as being with the Lord.  If that is the timing and sequence, then what happens at the time of the return of Christ when the mass resurrection  takes place and the old bodies are gathered up to be forever with the Lord???
