What does John 21:23 mean?
Modern Christians reading his passage may feel a combination of aggravation and reassurance. Jesus was asked to comment on the fate of the apostle John (John 21:20–21). He responded by refusing to make a prediction. He merely told Peter that John's fate was irrelevant to Peter's ministry. Even if John were to live forever—or at least until Jesus returned—it wouldn't change what Peter needed to do. Despite that, rumors spread that John was going live forever, a conclusion completely missing the point of what Jesus had said (John 21:22).In one sense, it's frustrating to know that misinformation can arise so quickly. In the time between Jesus' resurrection and John's writing of this gospel, a mistaken claim popped up that John needed to formally renounce. And yet, this is also an encouraging detail. This is among the latest-written works of the New Testament. That men like John are alive and able to refute mistakes strongly supports the accuracy of Scripture. These books were recorded and in circulation while eyewitnesses were still alive to rebuff false beliefs (John 21:24–25).
