Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written. John 21:25
As much of Christ’s sayings and doings is recorded as the mind of man can take in. It would not be good for the world to have more. The human mind, like the body, can only digest a certain quantity. The world could not contain more, because it would not. As many miracles, as many parables, as many sermons, as many conversions, as many words of kindness, as many deeds of mercy, as many journeys, as many prayers, as many warnings, as many promises, are recorded, as the world can possibly require. If more had been recorded they would have been only thrown away. There is enough to make every unbeliever without excuse, enough to show every inquirer the way to heaven, enough to satisfy the heart of every honest believer, enough to condemn man if he does not repent and believe, enough to glorify God. The largest vessel can only contain a certain quantity of liquid. The mind of all mankind would not appreciate more about Christ, if more had been written. There is enough and to spare. This witness is true. Let us deny it if we can.
And now let us close the Gospel of John with mingled feelings of deep humility and deep thankfulness. We may well be humble when we think how ignorant we are, and how little we comprehend of the treasures which this Gospel contains. But we may well be thankful, when we reflect how clear and plain is the instruction which it gives us about the way of salvation. The man who reads this Gospel profitably, is he who “believes that Jesus is the Christ, and, believing, has life through His Name.” Do we so believe? Let us never rest till we can give a satisfactory answer to that question!
