For John, it was simple. He wanted everyone to know the real Jesus, even those who got Jesus wrong. John knew about Jesus like no one else still alive in his time. He had been with Jesus when He wept in the Garden of Gethsemane, had watched Jesus raise Lazarus and others, and had stood at the foot of Jesus' cross with Mary. He had leaned on Jesus during the Last Supper, had run to Jesus' empty tomb with Peter, and had eaten with Jesus after his resurrection.
