OK, Here we go with my opinion. Scriptures listed at end of opinion. : D
First: In the Hebrew Scriptures, before the Christ, there is talk of resurection to earth. These folks understood this. They also knew there was a seed that would come from the Hebrew Genealogy that would bring peace and order back to the earth.
Equal Value for perfect life lost. '2nd Adam' in other words.
Second: After Christ's appearance a whole new concept was introduced which was foreign to the folks. HEAVENLY LIFE! When Jesus talked to Martha about Lazarus coming back, she understood about his coming back to her here on earth. John 11:5-44
Starting with the 12 Apostles, minus Judas, + Matthias, Jesus made it known that he was gathering persons to come rule with him in heaven as kings and priests. Making up his Bride Class.
After his own nation rejected Jesus...Got turned his attention to the nations to gather more for the Heavenly Kingdom. Acts 14:27; 15:14; 26:23 .... Ro. 11:13; 15:9
So there's more of a reason for a resurection to heaven than to be a beautiful flower or sit around and prop ones feet up from all your hard work here on earth.
I was taught this as a child, untill I learned better.
So, the A to the Q for me would be that one is Chosen to be a part of this new Government or Heavenly Rulership with Christ as Head. Which will be the new Jeruselem to rule over the inhabitants of this BEAUTIFUL EARTH, after the corrupt earthly rulers are extinguished. (Which we are ever closer to that Final War which will rid the earth of all Darkness and Evil to allow for the LONG awaited Paridise Earth where Righteousness will dwell.)
