When one is born from above, by GOD's Promise a spark of HIS Holy Spirit is placed int he newly cleansed soul of that believer / faither. As that one lives, being gradually raise up in the way that they should go, the spark refines the inward spirit of the man / woman / child. At the last Trumpet and Call of the Archangel, that spark zone will resonate instantly, changing the entire tissue base of that redeemed one, such that their body will no longer be in the same sapcetime coordinate system as those unsaved around them. Jesus described the event in Matthew's Gospel. He also introduced the Rapture TRUTH in John 14 when speaking to His disciples about going to prepare a place for them (and us) and coming back to get them to take them to the place He is preparing in the Father's House. All transformed faithers will be caught up into the clouds, to meet the Lord in the air. Seven years later, we will return with Him for the final destruction of all unbelievers and the devil and hid henchghouls.
It’s amazing to me that the Rapture deniers admit that Christians will leave the earth but are totally ignorant of the fact that when Jesus returns at the 2nd coming the living people on the earth go no where...They stay put on the earth...
