18:18-30 Many have a great deal in them very commendable, yet perish for lack of some one thing; so this ruler could not bear Christ's terms, which would part between him and his estate. Many who are loth to leave Christ, yet do leave him. After a long struggle between their convictions and their corruptions, their corruptions carry the day. They are very sorry that they cannot serve both; but if one must be quitted, it shall be their God, not their wordly gain. Their boasted obedience will be found mere outside show; the love of the world in some form or other lies at the root. Men are apt to speak too much of what they have left and lost, of what they have done and suffered for Christ, as Peter did. But we should rather be ashamed that there has been any regret or difficulty in doing it.
20. Thou knowest, &c.—Matthew (Mt 19:17) is more complete here: "but if thou wilt enter into life, keep the commandments. He saith unto him, Which—as if he had said, Point me out one of them which I have not kept?—"Jesus said, Thou shalt," &c. (Mt 19:17, 18). Our Lord purposely confines Himself to the second table, which He would consider easy to keep, enumerating them all—for in Mark (Mr 10:19), "Defraud not" stands for the tenth (else the eighth is twice repeated). In Matthew (Mt 19:19) the sum of this second table of the law is added, "Thou shalt love thy neighbor as thyself," as if to see if he would venture to say he had kept that.
