See this passage illustrated in the notes at Matthew 19:16-30.

Mark 10:17

Gone forth - From the place where he had been teaching.

Into the way - Into the road or path on his journey.

Running - Thus showing the intensity with which he desired to know the way of life. Zeal to know the way to be saved is proper, nor is it possible that it should be too intense if well directed. Nothing else is so important, and nothing demands, therefore, so much effort and haste.

There came one running - See the case of this rich young man largely explained on Matthew 19:16 (note), etc.

And when he was gone forth into the way,.... For when he had blessed the children he departed from the coasts of Judea, on the further side of Jordan, and steered his course towards Jerusalem, Mark 10:32, and as he was on the road thitherwards,

there came one running; a young man, a ruler among the Jews, and very rich, a person of great dignity, and large substance; he hearing that Christ was going from those parts, ran in great haste to him, to have some conversation with him, before he was entirely gone;

and kneeled to him; as a token of great respect and civility: some versions, as the Persic and Ethiopic, render it, "and worshipped him"; which must be understood not in a religious, but in a civil way: the words might be literally rendered, "and kneeled him"; and Dr. Lightfoot suspects, that more is meant than bending his knees to Christ; that he also might take hold of the knees of Christ, and kiss them, as was usual with the Jewish Rabbins, and which he illustrates by several instances:

and asked him, good master, what shall I do that I may inherit eternal life? This man, though a young man, and also a rich man, was thoughtful of the world to come, and the life of it: he believed there was an eternal life after this state of things, and so was no Sadducee; but he had wrong notions about the way and manner of attaining it: he thought it was to be had by the works of the law, which shows him to be a Pharisee; whereas eternal life is the gift of God, through the Messiah, the person he now applied to, and who had the words of eternal life; and to a more proper person he could not have put the question, he being himself the way, the truth, and the life, or the true way to eternal life: and had he attended to his own words, which suggest, that eternal life is an inheritance, he might have learned, that it is not to be acquired by the industry and works of men; but, that it is the bequest of our heavenly Father to his children, and comes by will, by promise, and as a free gift; so that it is not of the law; nor are they that are of the law heirs of it, Romans 4:14; See Gill on Matthew 19:16.

Running and kneeled

Two details peculiar to Mark.

{4} And when he was gone forth into the way, there came one running, and kneeled to him, and asked him, Good Master, what shall I do that I may inherit eternal life?

(4) Two things are to be greatly avoided by those who earnestly seek eternal life: the first is an opinion of their merits or deservings, which is not only understood, but condemned by the due consideration of the law: and the second is the love of riches, which turns aside many from that race in which they ran with a good courage.

10:17-22 There came one running. See notes on Mt 19:16-22. Compare Lu 18:18-22. Mark adds that the young man came running, and kneeled in the way. He alone tells us that Jesus beholding him loved him (Mr 10:21).

10:17 Mt 19:16; Lu 18:18.

Mr 10:17-31. The Rich Young Ruler. ( = Mt 19:16-30; Lu 18:18-30).

See on [1473]Lu 18:18-30.

10:17-22 This young ruler showed great earnestness. He asked what he should do now, that he might be happy for ever. Most ask for good to be had in this world; any good, Ps 4:6; he asks for good to be done in this world, in order to enjoy the greatest good in the other world. Christ encouraged this address by assisting his faith, and by directing his practice. But here is a sorrowful parting between Jesus and this young man. He asks Christ what he shall do more than he has done, to obtain eternal life; and Christ puts it to him, whether he has indeed that firm belief of, and that high value for eternal life which he seems to have. Is he willing to bear a present cross, in expectation of future crown? The young man was sorry he could not be a follower of Christ upon easier terms; that he could not lay hold on eternal life, and keep hold of his worldly possessions too. He went away grieved. See Mt 6:24, Ye cannot serve God and mammon.
