This verse in the King James

King James wording
These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.

The repeated “name” frames the promise: trust in the Son’s nature holds the certainty that the life of the age is already yours.

These words meet you in a trust directed toward the nature of the Son of God. They make knowing present: you have the life of the age now. The repeated trust returns you to the same nature on which that knowledge rests.

WHAT THIS UNDOES

It undoes the belief that this life is only a future reward: the verse says you have it now.

This verse uses the same Greek phrase, ⁨ζωὴ αἰώνιος⁩ (zōē aiōnios, life of the age), and locates that life in the Son. Verse 13 turns that given life into something you can know you have as you trust the Son’s nature.
