Many on five doves seem to think that those left behind are some how less holy.  But i have a suspicion that the saints left behind will serve a divine purpose.  They will be warriors and God will equip them (he is already preparing them) to help their family's and others left behind who need to learn about not taking the mark of the beast etc.  I also suspect that those left behind for Gods purposes will be the virgins spoken of in revelation.  These men will reign under Christ as princes in different places around the world once Christ returns in power and Glory.  The mind set of these people will be much like Jesus when he said "if its possible take this cup of suffering from me, but your will be done Father, not mine".  The greatest difficulty will be the mental grappling of wanting to go in the rapture but at the same time knowing it is best to obey the Father and persevere through the tribulation doing all God has called us to do.  Simply pray about this.  I have had something to this effect prophesied over me at 2 different Churches.  Once called out among a Church full of people and another time someone privately prophesying about God developing warrior traits and how i shouldn't be ashamed of this.  I may not have all the details right but we should pray about these things so we are not confused.  Another thing, do everything you can to bless Israel.  I also think it's a good idea to keep the Sabbath and kosher diet.  These were part of Christ's everyday culture.
