Eternal Life is often mistaken for Immortality. The two are not the same.
Immortality pertains to a body that's immune to death. Eternal Life, on the
other hand, pertains to a soul that's immune to death.
It's possible for people to obtain eternal life prior to obtaining immortality.
For example: Christ had eternal life all along (John 5:26, 1John 1:1-2) but
according to Rom 6:9 and Rev 1:18, he didn't obtain immortality till after his
crucified dead body was restored to life.
Likewise his believing followers have eternal life now (John 5:24, 1John
5:13) but according to Rom 8:23-25, 1Cor 15:51-53, and 1Thss 4:14-17
they won't obtain immortality until their resurrections.
Eternal Life and Immortality are very important benefits primarily because
they protect people from the second death depicted by Rev 20:11-15.
FAQ: Don't people in perdition have eternal life? Wouldn't they have to in
order to be there forever?
REPLY: If they had eternal life; they wouldn't be in perdition.
● John 3:16-17 . . God so loved the world that He gave His one and only
son, that whoever believes in him shall not perish but have eternal life. For
God did not send His son into the world to condemn the world, but to save
the world through him.
● John 5:24 . . I assure you; those who listen to my message, and believe in
God who sent me, have eternal life. They will never be condemned for their
sins, but they have already passed from death into life.
● John 10:27-28 . . My sheep hear my voice, and I know them, and they
follow me: and I give unto them eternal life; and they shall never perish.
The thing is: eternal life has more to do with divine qualities than it does
with longevity. Folks in perdition are there because they had only human
nature when they passed on instead departing with the divine nature
mentioned in 2Pet 1:2-4.
