I must work the works of him that sent me, while it is day: the night comes, when no man can work.
All Commentaries on John 9:4 Go To John 9
That is, I must manifest Myself, and do the things which may show that I do the same things with the Father; not things similar, but, the same, an expression which marks greater unvaryingness, and which is used of those who do not differ ever so little. Who then after this will face Him, when he sees that He has the same power with the Father? For not only did He form or open eyes, but gave also the gift of sight, which is a proof that He also breathed in the soul. Since if that did not work, the eye, though perfected, could never see anything; so that He gave both the energy which is from the soul, and gave the member also possessing all things, both arteries and nerves and veins, and all things of which our body is composed.
I must work while it is day.
What mean these words? To what conclusion do they lead? To an important one. For what He says is of this kind. While it is day, while men may believe in Me, while this life lasts, I must work.
The night comes, that is, futurity, when no man can work.
He said not, when I cannot work, but, when no man can work: that is, when there is no longer faith, nor labors, nor repentance. For to show that He calls faith, a work, when they say unto Him, What shall we do, that we might work the works of God? John 6:28, He replies, This is the work of God, that you believe in Him whom He has sent. How then can no man work this work in the future world? Because there faith is not, but all, willingly, or unwillingly, will submit. For lest any one should say that He acted as He did from desire of honor, He shows that He did all to spare them who had power to believe here only, but who could no longer there gain any good thing. On this account, though the blind man came not to Him, He did what He did: for that the man was worthy to be healed, that had he seen he would have believed and come to Christ, that had he heard from any that He was present, he would not even so have been neglectful, is clear from what follows, from his courage, from his very faith. For it was likely that he would have considered with himself, and have said, What is this? He made clay, and anointed my eyes, and said to me, 'Go, wash;' could he not have healed me, and then have sent me to Siloam? Often have I washed there with many others, and have gained no good; had he possessed any power, he would while present have healed me. Just as Naaman spoke respecting Elisha; for he too being commanded to go wash in Jordan, believed not, and this too when there was such a fame abroad concerning Elisha. 2 Kings 5:11 But the blind man neither disbelieved, nor contradicted, nor reasoned with himself, What is this? Ought he to have put on clay? This is rather to blind one the more: who ever recovered sight so? But he used no such reasonings. Do you see his steadfast faith and zeal?
The night comes. Next He shows, that even after the Crucifixion He would care for the ungodly, and bring many to Himself. For it is yet day. But after that, He entirely cuts them off, and declaring this, He says,
