Not everyone was called into God’s service, with some of dubious intent taking a form of it upon themselves, claiming… “have we not…?” with the expectation of the SHOW of great reward, but theirs was a shallow and hollow gesture which had its own reward (Mt 6:2, 5, 16). Again it’s not a case of postmortem-ism but present service to God which had Jesus saying elsewhere… “many are called, but few are chosen” (Mt 20:16; 22:14). Typically of course such has been Calvinised into a postmortem experience of either heaven or hell, but that IMO is incorrect. The way into the fullness of this life of service in God was narrow with many missing it, finding rather the broad road of self, leading to desperation, desolation and despair, i.e., destruction (Mt 7:13-14).
Gideon in the OT is a good source for an example of this in that MANY were called to serve Israel and yet due to various limits did not make the cut into the service being sought. BUT just because some were being pruned off and the numbers whittled down did NOT mean those being cut were subject to loss in terms of a devastating postmortem end, no. They were simply NOT CHOSEN for THAT particular redemptive or delivering event (Judg 7:1-7). Thus the likes of Rom 9:11 can be understood in exactly the same manner, i.e., in terms of redemptive purposes and calling, as opposed to the tradition of certain postmortem outcomes.
