This is a critical error because the Bible plainly shows they will have different natures after the resurrections. Several people died and were brought back to life. Since they later died again, they were still mortal. This shows we cannot assume all resurrections result in immortality. This reiterates the fact that believers will be immortal, since they cannot die.
Immortality is conditional.
Immortalists do not offer any Scriptural response to this powerful evidence. Nevertheless, they force their assumption that nonbelievers will be immortal into the Word of God. If we accept what the Bible says, we reject their doctrine. Several others passages show nonbelievers do not have an eternal existence. The Bible says many times that believers have eternal life, and never says nonbelievers have eternal life.
