The works of him ... - The works of beneficence and mercy which God has commissioned me to do, and which are expressive of his goodness and power. This was on the Sabbath day John 9:14; and though Jesus had endangered his life (John 5:1-16 by working a similar miracle on the Sabbath, yet he knew that this was the will of God that he should do good, and that he would take care of his life.

While it is day - The day is the proper time for work - night is not. This is the general, the universal sentiment. While the day lasts it is proper to labor. The term "day" here refers to the life of Jesus, and to the opportunity thus afforded of working miracles. His life was drawing to a close. It was probably but about six months after this when he was put to death. The meaning is, My life is near its close. While it continues I must employ it in doing the works which God has appointed.

The night cometh - Night here represents death. It was drawing near, and he must therefore do what he had to do soon. It is not improbable, also, that this took place near the close of the Sabbath, as the sun was declining, and the shades of evening about to appear. This supposition will give increased beauty to the language which follows.

No man can work - It is literally true that day is the appropriate time for toil, and that the night of death is a time when nothing can be done. Ecclesiastes 9:10; "there is no work, nor device, nor knowledge, nor wisdom in the grave." From this we may learn:

1. that it is our duty to employ all our time in doing the will of God.

2. that we should seek for opportunities of doing good, and suffer none to pass without improving it. We go but once through the world, and we cannot return to correct errors, and recall neglected opportunities of doing our duty.

3. We should be especially diligent in doing our Lord's work from the fact that the night of death is coming. This applies to the aged, for they must soon die; and to the young, for they may soon be called away from this world to eternity.

While it is day - Though I plainly perceive that the cure of this man will draw down upon me the malice of the Jewish rulers, yet I must accomplish the work for which I came into the world whole it is day - while the term of this life of mine shall last. It was about six months after this that our Lord was crucified. It is very likely that the day was now declining, and night coming on; and he took occasion from this circumstance to introduce the elegant metaphor immediately following. By this we are taught that no opportunity for doing good should be omitted - Day representing the opportunity: Night, the loss of that opportunity.

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 Isaiah 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. This life is but short, it is but as the length of a day; a great deal of business is to be done; and death is hastening on, which will put a period to all working.

I must work (ἐμὲ δεῖ ἐργάζεσθαι)

The best texts read ἡμᾶς, us, instead of ἐμὲ, me. Literally, it is necessary for us to work. The disciples are thus associated by Jesus with Himself. Compare John 3:11.

Sent me, not us

The Son sends the disciples, as the Father sends the Son.

{2} I must work the works of him that sent me, while it is {b} day: the night cometh, when no man can work.

(2) The works of Christ are is it were a light, which enlighten the darkness of the world.

(b) By day is meant the light, that is, the enlightening doctrine of the heavenly truth: and by night is meant the darkness which comes by the obscurity of the same doctrine.

9:4 The night cometh, when no man can work. The works of God are to be made manifest in the blind man; Christ must work those works while the short day of life lasteth. His night of death was near. Nor is ours far off.

9:4 The night is coming - Christ is the light. When the light is withdrawn night comes, when no man can work - No man can do any thing toward working out his salvation after this life is ended. Yet Christ can work always. But he was not to work upon earth, only during the day, or season which was appointed for him.

4. I must work the works of him that sent me, &c.-a most interesting statement from the mouth of Christ; intimating, (1) that He had a precise work to do upon earth, with every particular of it arranged and laid out to Him; (2) that all He did upon earth was just "the works of God"-particularly "going about doing good," though not exclusively by miracles; (3) that each work had its precise time and place in His programme of instructions, so to speak; hence, (4) that as His period for work had definite termination, so by letting any one service pass by its allotted time, the whole would be disarranged, marred, and driven beyond its destined period for completion; (5) that He acted ever under the impulse of these considerations, as man-"the night cometh when no man (or no one) can work." What lessons are here for others, and what encouragement from such Example!

9:1-7 Christ cured many who were blind by disease or accident; here he cured one born blind. Thus he showed his power to help in the most desperate cases, and the work of his grace upon the souls of sinners, which gives sight to those blind by nature. This poor man could not see Christ, but Christ saw him. And if we know or apprehend anything of Christ, it is because we were first known of him. Christ says of uncommon calamities, that they are not always to be looked on as special punishments of sin; sometimes they are for the glory of God, and to manifest his works. Our life is our day, in which it concerns us to do the work of the day. We must be busy, and not waste day-time; it will be time to rest when our day is done, for it is but a day. The approach of death should quicken us to improve all our opportunities of doing and getting good. What good we have an opportunity to do, we should do quickly. And he that will never do a good work till there is nothing to be objected against, will leave many a good work for ever undone, Ec 11:4. Christ magnified his power, in making a blind man to see, doing that which one would think more likely to make a seeing man blind. Human reason cannot judge of the Lord's methods; he uses means and instruments that men despise. Those that would be healed by Christ must be ruled by him. He came back from the pool wondering and wondered at; he came seeing. This represents the benefits in attending on ordinances of Christ's appointment; souls go weak, and come away strengthened; go doubting, and come away satisfied; go mourning, and come away rejoicing; go blind, and come away seeing.
