'Eternal Life' in the Bible

to those who by persistence in doing good seek [unseen but certain heavenly] glory, honor, and immortality, [He will give the gift of] eternal life.

so that, as sin reigned in death, so also grace would reign through righteousness which brings eternal life through Jesus Christ our Lord.

But now since you have been set free from sin and have become [willing] slaves to God, you have your benefit, resulting in sanctification [being made holy and set apart for God’s purpose], and the outcome [of this] is eternal life.

For the wages of sin is death, but the free gift of God [that is, His remarkable, overwhelming gift of grace to believers] is eternal life in Christ Jesus our Lord.
