Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written.
John closes with a hyperbole which tells us that there is a lot more about Jesus than we can ever know. The implication is, however, that there is nothing else that is essential to know. What is written is sufficient to bring us into the relationship God has designed for us.
In a moral sense, this statement of John’s is quite literal. The world could not contain any more of the gospel than what it has. The word translated as “contain” or “have room” here is the same word translated as “place” or “room” in (John 8:37).
John 8:37 I know you are Abraham’s descendants. Yet you are ready to kill me, because you have no room for my word.
Morris finishes his fine commentary on this verse by observing that “It is well for us to be appreciative of the knowledge we have and to show a due gratitude to God for what He has revealed. But we should not exaggerate. Our knowledge of the truth is at best partial. The reader who appreciates the significance of these final words is kept humble.” Amen.
John wrote this wonderful account of our Lord so that we who read it may believe in Jesus and trust in His saving grace (John 19:35). It is my prayer that the Gospel of John has done exactly that and has helped you to know our wonderful Lord better than you ever have before. My challenge to you is to keep growing in your relationship with Him by spending time with Him in His Word and in prayer.
John 19:35 The man who saw it has given testimony, and his testimony is true. He knows that he tells the truth, and he testifies so that you also may believe.
