There is not a single verse in any posts above mentioning or requiring any postmortem occurrence of affliction… not one.
To be “salted with fire” was neither a postmortem text nor even a text applicable to humanity in toto. Such was spoken TO and applicable Of Jesus’ followers… which IF ONLY those peddling other scenarios would CHECK the context of the passage such is there in black and white and requires no massaging of dubious theologies into it… Mk 9:30-31, 33-34, 38, 50.
In Jewish practice, all sacrifices were to be salted and no sacrifice was acceptable without it…
And every offering of your grain offering you shall season with salt; you shall not allow the salt of the covenant of your God to be lacking from your grain offering. With all your offerings you shall offer salt. Cf. Ezek 43:24; Ex 30:35
Jesus’ being salted had nothing to do with “postmortem correction/s” but was very much indicative of the antemortem (this life) nature of the preparatory effect persecution was about to bring. According to the context of the passage such salting would indeed be limited and yet fully inclusive of all in that grouping, i.e., the disciples — all disciples in faithful service were a “living sacrifice” (Rom 12:1) and would be tried by the fires of persecution.
Again… as salt accompanied OT sacrifices so would the soon coming fire of trial and tribulation accompany and try (refine) NT believers…
…that the genuineness of your faith, being much more precious than gold that perishes, though it is tested by fire, may be found to praise, honor, and glory at the revelation of Jesus Christ. … Beloved, do not think it strange concerning the fiery trial which is to try you, as though some strange thing happened to you.
This then as I understand it is what Jesus meant when he said… “For everyone will be seasoned with fire, and every sacrifice will be seasoned with salt.” And this then is the same as Paul speaks of here…
…each one’s work will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one’s work, of what sort it is. If anyone’s work which he has built on it endures, he will receive a reward. If anyone’s work is burned, he will suffer loss; but he himself will be saved, yet so as through fire.
Thus ‘being salted with fire’ speaks NOT to some universal global principle, or other, awaiting all and sundry postmortem, NO… this was time specific and is CLEAR from the texts… pertinent TO believers of that day — no more and no less!
Even John the Baptist speaking of Jesus’ ministry said… “He will baptise with the Holy Spirit and fire” — such ‘fire’ was an indicator of the afflictions those following their Master would likewise face, thus Jesus’ words here…
But Jesus said to them, “You do not know what you ask. Are you able to drink the cup that I drink, and be baptized with the baptism that I am baptized with?” They said to Him, “We are able.” So Jesus said to them, “You will indeed drink the cup that I drink, and with the baptism I am baptized with you will be baptized.
We see then this theme of affliction in service of God following and flowing through the rest of the NT story, as per the likes of…
But the Lord said to him, “Go, for he is a chosen vessel of Mine to bear My name before Gentiles, kings, and the children of Israel. For I will show him how many things he must suffer for My name’s sake.”
Therefore I ask that you do not lose heart at my tribulations for you, which is your glory.
…that I may know Him and the power of His resurrection, and the fellowship of His sufferings, being conformed to His death,…
…meanwhile praying also for us, that God would open to us a door for the word, to speak the mystery of Christ, for which I am also in chains,…
And you became followers of us and of the Lord, having received the word in much affliction, with joy of the Holy Spirit, —therefore, brethren, in all our affliction and distress we were comforted concerning you by your faith.
Thus the case for supposed postmortem affliction… well, hmmm
