24This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true. 25And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
Comment: The author of the gospel here affirms that what is recorded is true because he saw the events with his own eyes. Then a "we" sentence is used as further affirmation. Whether these are additional witnesses agreeing with the veracity of the statements or just the author referring to himself, we cannot be certain. Even if the author were referring to himself, the statement is emphatic and still would not have been said unless there were other reliable witnesses that could have been included in the statement. Once again, we have another author with just as much conviction as Paul that the events he witnessed were true except this author's witness of the resurrected Jesus preceded Paul's by several years. We know Paul's encounter was later because Paul witnessed the resurrected Jesus on the road to Damascus with the intent to bring Jewish Christians back to Jerusalem for punishment several years after the resurrection had occurred. John, however, was one of Jesus' original disciples. And yet, despite the fact that Paul was not an original disciple and in fact wanted Christianity eliminated, witnessed the resurrected Jesus even as John had several years earlier. Certainly the disparity in the circumstances and timing establishes the fact there were independent witnesses to Jesus' resurrection.
