'Eternal' in the Bible

But because of this I was shown mercy, in order that in me foremost, Christ Jesus might demonstrate his total patience, for an example for those who are going to believe in him for eternal life.

Fight the good fight of the faith; take hold of the eternal life to which you were called, and confessed the good confession in the presence of many witnesses.

the [one who] alone possesses immortality, who lives [in] unapproachable light, whom no human being has seen nor is able to see, to whom [be] honor and eternal power. Amen.
