How do we know the words we read in the Bible are true? This verse offers a powerful, communal affirmation at the very end of the Gospel of John.
A Witness's Lasting Impact
John 21:24 serves as a closing endorsement, not just for the final chapter, but for the entire Gospel. It identifies the author as "the disciple whom Jesus loved" – the one who bore witness and wrote these accounts.
A Twofold Testimony:
- Bearing Witness (Present Tense): The disciple's testimony wasn't just a one-time event; it was an ongoing reality. He was still alive and testifying about Jesus, both in person and through his writings.
- Having Written (Past Tense): This acknowledges the completed act of writing the Gospel, distinguishing the act of recording from the continuing practice of testifying.
The use of "we know" suggests a community's shared conviction. It’s as if the early church, familiar with the disciple and his writings, adds their collective voice, affirming the truthfulness of his account. This isn't just one person's claim; it's a divinely sanctioned, communal guarantee.
