John 9:4

I must work the works of him that sent me,.... This shows, that the works of God, that were to be manifest, were to be done by Christ: many were the works which the Father gave him to do, and which he undertook to perform; and therefore there was a necessity of doing them, as principally the work of redemption, by fulfilling the law, and satisfying justice: and besides this, there were the preaching of the Gospel, and doing of miracles, and among these was this of giving sight to the blind, see Isa 35:5, both in a natural and spiritual sense: and with a view to this he speaks of the works he mast do,while it is day; while the day of life lasts, for in the grave there is no work nor device:the night cometh when no man can work; meaning the night of death, and of the grave, and suggesting his own death hereby, that he had but a little time to be in this world, and therefore would make the best use of it, to do the will and work of his Father that sent him; and which should be a pattern to us.
