When are believers in Messiah Jesus "gathered unto him"?
2 Th 2:1-2 (KJV 2009)
1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
Aside from the question of "when?", one needs perhaps first clarify the "what?" of this "gathering unto him" ... is this talking about the type "physically disappear in the air" as some bumper stickers suggest ("at the gathering together, this car will be without a driver") ??
Which details does the context provide for understanding the passage correctly? When was the text written? to whom is it written? does it apply to Christians in general today? if so, to what degree and how?
Text based input will be appreciated.
