Hi,
I have posted on this site in the past regarding what i believe to be signs but to my mind these signs are to do with Gods coming judgement, not the rapture.  When the word says he will keep us, i believe there is good reason to believe it means he will keep us through it, not remove us.  God can translate people as he did with Phillip to make a doctrine out of it and call it the "pre trib rapture" is misleading to many as perhaps God would have us prepare for our families.  Can you imagine why satan would perpetuate the rapture lie as he knows the destruction is coming and he also knows that those who are unprepared (water, food supplies etc) will perish quickly.  So dont give up that God may translate you as he did Phillip but also prepare in the natural as Joseph did and as Noah did.  For what its worth i believe there is only a very small remnant of believers who are trult following Gods ways.  It is not a denomination, it is a remnant.  This remnant knows Gods Sabbath and tries to keep it holy.  This remnant is also likely to be the 144000 but im not dogmactic about that.
