Jesus answered, Are there not {c} twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world.

(c) All things happen in a proper way and are brought to pass in their due time.

People's New Testament

11:9 Are there not twelve hours in the day? This is his answer to the protest of his disciples against going to Judea again, where the Jews seek his death. He sees his course clearly and is walking in the day.

Wesley's Notes

11:9 Are there not twelve hours in the day? - The Jews always divided the space from sunrise to sunset, were the days longer or shorter, into twelve parts: so that the hours of their day were all the year the same in number, though much shorter in winter than in summer. If any man walk in the day he stumbleth not - As if he had said, So there is such a space, a determined time, which God has allotted me. During that time I stumble not, amidst all the snares that are laid for me. Because he seeth the light of this world - And so I see the light of God surrounding me.

Jamieson-Fausset-Brown Bible Commentary

9. Jesus answered, Are there not twelve hours in the day?-(See on [1829]Joh 9:4). Our Lord's day had now reached its eleventh hour, and having till now "walked in the day," He would not mistime the remaining and more critical part of His work, which would be as fatal, He says, as omitting it altogether; for "if a man (so He speaks, putting Himself under the same great law of duty as all other men-if a man) walk in the night, he stumbleth, because there is no light in him."

Matthew Henry's Concise Commentary

11:7-10 Christ never brings his people into any danger but he goes with them in it. We are apt to think ourselves zealous for the Lord, when really we are only zealous for our wealth, credit, ease, and safety; we have therefore need to try our principles. But our day shall be lengthened out, till our work is done, and our testimony finished. A man has comfort and satisfaction while in the way of his duty, as set forth by the word of God, and determined by the providence of God. Christ, wherever he went, walked in the day; and so shall we, if we follow his steps. If a man walks in the way of his heart, and according to the course of this world, if he consults his own carnal reasonings more than the will and glory of God, he falls into temptations and snares. He stumbles, because there is no light in him; for light in us is to our moral actions, that which light about us to our natural actions.
