And Jesus looking upon him loved him. ( ἐμβλέψας αὐτῶ ἠγάπησεν αὐτόν) This is another of St. Mark's graphic touches—an exquisite piece of word-painting, probably supplied to him by St. Peter.
The words express most vividly an earnest, tender, searching look. They seem, if it may be said reverently, to combine the Divine penetration with human sympathy and compassion. The counsel of our Lord which follows was not a general command, but a particular precept, which the young ruler specially needed.
One thing thou lackest. In St. Matthew (Matthew 19:21) the words are, "If thou wouldest be perfect." But our Lord's words here, "One thing thou lackest," fit in excellently with the young ruler's question given just before in St.
Matthew, "What lack I yet?" showing a substantial unity in the narrative, with just that variety which we should expect in the account of the same incident given by two independent but equally trustworthy witnesses.
The "one thing thou lackest" of St. Mark, and "if thou writ be perfect of St. Matthew, both point to the same conclusion—that our Lord's object was to reveal this young man to himself. His stumbling-block was his wealth; and so our Savior at once pierces his besetting sin of covetousness.
The precept was a special counsel to him; it directed him to do something which, as our Lord saw, was in his case necessary to his salvation. He could not follow Christ without parting with this sin, and with that which ministered to it.
This was his particular spiritual difficulty.
