I’ve actually shared this with you before Revival, but here goes again. The first place I see post-mortem salvation is in the story of Jonah, who drowned, was in Sheol (grave, realm of the dead), in torment repented and cried out to God who saved him and even restored him to life.
Next I see the concept of post-mortem salvation in Paul’s affirmation of baptism for the dead in 1 Cor. 15. He notes this in passing as evidence of why the Corinthians should believe in the ressurection of the dead. But none-the-less he speaks of it affirmatively. During the first century, prayers, alms and even baptism for the dead was a common practice meant to aid departed loved ones in their transition into the presence of God.
Next, Peter speaks of Jesus preaching to the spirits in prison, particularly those who rejected the Word and Salvation of God under Noah’s ministry. He preached to them so that they might be judged and have life.
And of course, “IF” John’s vision in Revelation is meant to be understood futuristically, then we have the nations and kings who throughout the other visions in Revelation are subject to the spirit of the anti-Christ, eventually worshipping Jesus, entering the New Jerusalem and paying homage to God.
Of course, scripture is by far predominantly our present reality, being delivered from this “present evil age” as Paul calls it, and having a relationship with God NOW; not about what happens in the after-life. Even so, to me this is more than sufficient evidence to indicate that there will be plenty of repentance going on in the life-to-come. In fact, it was studying scripture concerning Judgment and punishment of sin that freed be to believe that Jesus is the savior of all for I found that the purpose of God’s judgment and punishment of sin is for our good, to change us, that though weeping lasts for a season, joy eventually comes.
But I’ve shared this before.
Note that Paul does not say “spiritual death”, but that is what you’ve added. Without further qualification, based upon “death’s” most common usage in Paul and elsewhere in scripture, if we must “assume” a meaning then the most common one would be the correct one to assume, which is normal physical death. Because Adam sinned we shall all die. Paul has just affirmed this repeatedly in the previous chapter. To read into it “spiritual death” is, well, to “read it into” this passage, eisegesis.
First note that you’re pulling a piece of a passage from a different book, author, context and trying to use it to prove a point about a completely different passage. It’s much better, I believe, to base one’s understanding of any given passage upon its own context.
In the context of this passage, Jesus is affirming that it is through faith in Him that people have age-to-come (aionian, eternal) life. He is not addressing what happens to people post-mortem, but is addressing the reality that people can have, experience age-to-come life in the present though we be surrounded by death. To read into this some affirmation about there being no possibility of repentance and reconciliation through Christ in the life-to-come is, well again, “reading into it”, eisegesis. I believe it’s best to stick with what the passage actually says, and not read into it more than what is there.
