When Jesus heard that, he said, This sickness is not unto death - to result in death.
but for the glory of God, that the Son of God may be glorified thereby - that is, by this glory of God. (See Greek.) Remarkable language this, which from creature lips would have been intolerable. It means that the glory of God manifested in the resurrection of dead Lazarus would be shown to be the glory, personally and immediately, of THE SON.
