Both these terms are generally misunderstood because of traditions of men. And from this came the doctrine of the immortality of the soul. So then resurrection is not really needed, and salvation has come to mean avoiding the punishments and tortures in hell for sins.
Immortal soul is a term foreign to the Scriptures.
And hell is simply the grave in which there is no knowledge or device, the dead know not anything. So in the light of these things, many have to revise their ideas of resurrection and salvation. In the first place, these two are inseparable. Salvation includes resurrection. Since resurrection is a part of salvation, and that is for the believer, then the unbeliever can have no part in it.
