Yes here it is, the verse: both the just and unjust get resurrected, so I take this to mean not just christians are raised from the dead, but everyone.
Act 24:15 And have hope toward God, which they themselves also allow, that there shall be a resurrection of the dead, both of the just and unjust.
The Pharisees in Jesus's time believed in an immortal soul and that it existed in a future state.
Imagine that , everyone from Nero, Cleopatra, Hilter, Pol Pot, Stalin, etc, will be raised up from the dead and you might get to see them. Then they get thrown into the Lake of Fire. The first death, only the body dies. The second death, both body and soul die. This Lake of Fire is something that can destroy not just physical bodies but also destroy spiritual bodies too. That's why the devil and all his angels, demons and other evil spiritual creatures will be cast into the Lake of Fire, the Lake of Fire can destroy them for good. Other people believe the spiritual bodies will be floating around in the lake of fire being tortured forever but I dont believe that, i think a death of the soul is a cease to exist , not a torture of the soul.
