At Romans 6:1-14, we read in part, but especially at 6:7, " For he who has died has been freed from sin. ... We have died with respect to the wrath that sin incurs, having had our sins forgiven".
Now stop and think. If people who are died before Armageddon have all their sins forgiven, will it be a matter of justice for the God of Love to destroy a sizeable number of people who have not been fortunate enough to die before the Big A? In otherwords, its it a crime to be found living during the the time it happen? What do you think?
