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. He has no salvation, hence no resurrection. Those who profess to believe that there is a universal salvation for all men, then must also believe in a universal resurrection. But this is not to be found in the Scriptures.
Salvation here covers quite a bit.
It is the Lord, His coming, the raising of the dead and the change of the believers that are alive at His coming. This is their salvation. Again the second coming and resurrection are the salvation the Hebrews were to look for. So we have to conclude that salvation includes resurrection. Even those who are not overcomers will be raised.
