It’s a nice idea with no scriptural support that I’ve ever seen, that Christians have a second chance after death.
As I mentioned, your concept of Purgatory has clear roots in the Hebrew Sheol and appears to me to have been a survival of it. But, looking at every scriptural reference to the Crucifixion and Resurrection of Jesus Christ, as well as the New Testament scriptures referencing spiritual matters pertaining to the circumstance of believers as well as nonbelievers after physical death, it is clear that such a place no longer exists for Christians and most likely ceased to apply at all after Jesus Christ freed the righteous dead from Paradise, which was Old Testament as you mentioned.
Everything changed with the Resurrection. There is no longer any need to wait in a waiting place. Waiting for what? Not our Savior, He is risen. Purification, by fire is the belief, correct me if I’m mistaken, based upon one passage of scripture, the interpretation of which flies in the face of the rest of New Testament scripture, in order to support Purgatory.
sola scriptura is a nice idea with no scriptural support either.
Good night.
If this is your view of Purgatory, it's incorrect. Those in Purgatory are heaven-bound, that judgement has already been made, no second chance needed.
