After nearly nine months of study on the topic of “conditional immortality” including thousands of pages of material and many hours of online debates, lectures, and conferences, I am convinced that conditional immortality is based on theologically systematic and hermeneutically sound exegesis of scripture. Probably, the most comprehensive publications on this topic are “The Fire That Consumes” by Edward Fudge (my favorite) and “Rethinking Hell” which is a collection of views by a compendium of authors.
Traditionally, most Christians have believed that those who die in unbelief will ultimately be raised immortal and live forever in hell to suffer mental and physical torment for eternity as punishment for their sins.
Conditionalists, however, believe that Scripture consistently teaches that God alone is immortal (1Tim 6:15,16) and that He will grant immortality and eternal life only to those who meet the condition of saving faith in Christ. Everyone else—the unsaved—will be resurrected, judged and then punished for a time (whatever time God determines is just) and then suffer a second, irreversible death, perishing forever and ceasing to consciously exist.
Here is an excellent presentation by Edward Fudge. https://edwardfudge.com/cat…/videos/the-fire-thatconsumes/
