'Eternal' in the Bible

For whoever wishes to save his life [in this world] will [eventually] lose it [through death], but whoever loses his life [in this world] for My sake will find it [that is, life with Me for all eternity].

[For the Son of Man has come to save that which was lost.]

And someone came to Him and said, “Teacher, what [essentially] good thing shall I do to obtain eternal life [that is, eternal salvation in the Messiah’s kingdom]?”

When the disciples heard this, they were completely astonished and bewildered, saying, “Then who can be saved [from the wrath of God]?”

And everyone who has left houses or brothers or sisters or father or mother or children or farms for My name’s sake will receive many times as much, and will inherit eternal life.

“Then the King will say to those on His right, ‘Come, you blessed of My Father [you favored of God, appointed to eternal salvation], inherit the kingdom prepared for you from the foundation of the world.

“Then He will say to those on His left, ‘Leave Me, you cursed ones, into the eternal fire which has been prepared for the devil and his angels (demons);

Then these [unbelieving people] will go away into eternal (unending) punishment, but those who are righteous and in right standing with God [will go, by His remarkable grace] into eternal (unending) life.”
