John 9:4 - Joseph Benson’s Commentary on the Old and New Testaments

I must work the works of him that sent me Called in the preceding verse the works of God; that is, I must not cease doing this, however the malice of the Jews may be irritated thereby; I must not desist from doing the will of my heavenly Father, in order to please them; while it is day While I have an opportunity; while the time lasts, which is appointed to work in, and while the light lasts, which is given to work by. Observe, reader, Christ himself had his day; 1st, All the business of the mediatorial kingdom was to be done within the limits of time, and in this world; for at the end of the world, when time shall be no more, the kingdom shall be delivered up to God: even the Father, and the mystery of God shall be finished. 2d, All the work he had to do in his own person, here on earth, to set us an example of holy living, was to be done before his death. The time of his abode in this world was the day here spoken of. And the time of our life is our day, in which it concerns us to do the work of the day. During the day of life we must be busy, and that in doing the work appointed us: it will be time enough to rest when our day is ended. Our Lord adds, The night cometh, when no man can work As if he had said, I see death approaching, which, as it puts a period in general to human labours, so will close the scene of such labours as these, and remove me from the converse and society of men. The period of his opportunity for doing the will of his Father, and glorifying him on earth, was at hand, and therefore he would lose no time, but be active and laborious. Thus, the consideration of our death approaching, should quicken us to a diligent improvement of all the opportunities of life, both for doing and gaining good. The night cometh It will come certainly, and may come soon and suddenly: and when it comes we cannot work, because the light afforded us to work by will be extinguished, and the time allotted us to work in will then be expired. When the night comes, the labourers must be called. They must then show their work, and receive according to the deeds done in the body: for then the time of probation will be ended, and the time of retribution begun.
