(25) But first must he suffer many things.--See Notes on Matthew 16:21; Matthew 17:22. The interposition of this prophecy of the Passion in a discourse which bears primarily on the Second Advent is an individualising feature of this record of St. Luke's.

Verse 25. - But first must he suffer many things, and be rejected of this generation. But, and here again he repeats "as a solemn refrain to all his teaching," the warning to his own of the fearful end fast coming on him. If he is to come again with glory, he must first go away with shame, persecuted, forsaken, by the generation then living. The suffering Messiah must precede the glorified Messiah. After this rejection and suffering would begin the period alluded to above (ver. 22) as the time when men should long to have him only for one day in their midst. During this period Messiah should continue invisible to mortal eye. How long this state was to continue, one century or - (eighteen have already passed), Jesus himself, in his humiliation, knew not; but he announced (vers. 26-30) that a gloomy state of things on earth would be brought to a close by his reappearance. Ah! "when the Son of man cometh, shall he find faith on the earth?'

17:20-37 The kingdom of God was among the Jews, or rather within some of them. It was a spiritual kingdom, set up in the heart by the power of Divine grace. Observe how it had been with sinners formerly, and in what state the judgments of God, which they had been warned of, found them. Here is shown what a dreadful surprise this destruction will be to the secure and sensual. Thus shall it be in the day when the Son of man is revealed. When Christ came to destroy the Jewish nation by the Roman armies, that nation was found in such a state of false security as is here spoken of. In like manner, when Jesus Christ shall come to judge the world, sinners will be found altogether regardless; for in like manner the sinners of every age go on securely in their evil ways, and remember not their latter end. But wherever the wicked are, who are marked for eternal ruin, they shall be found by the judgments of God.But first must he suffer many things,.... By cruel mockings, spitting, buffeting, scourging, and, at last, death itself; all which must be, and were before his day came, or he entered into his glory, or came in it:

and be rejected of this generation; as the Messiah, and be treated with the utmost scorn and contempt, and in the most base and ignominious manner: being put to the death of the cross, and hanged upon the accursed tree: all which were necessary, "must" be; on account of the purposes and decrees of God; the covenant engagements of Christ; the predictions of the prophets of the Old Testament, and his own; and the salvation of his people.
