So Christ answers the question by quoting the second half of the Decalogue, which deals with the homeliest duties, and appending to it the summary of the law, which requires love to our neighbour as to ourselves. Why does He omit the earlier half? Probably because He would meet the error of the question, by presenting only the plainest, most familiar commandments, and because He desired to excite the consciousness of deficiency, which could be most easily done in connection with these.
There is a touch of impatience in the rejoinder, 'All these have I kept,' and more than a touch of self-satisfaction. The law has failed to accomplish one of its chief purposes in the young man, in that it has not taught him his sinfulness. No doubt he had a right to say that his outward life had been free from breaches of such very elementary morality which any old woman could have taught him. He had never gone below the surface of the commandments, nor below the surface of his acts, or he would not have answered so jauntily. He had yet to learn that the height of 'goodness' is reached, not by adding some strange new performances to the threadbare precepts of everyday duty, but by digging deep into these, and bottoming the fabric of our lives on their inmost spirit. He had yet to learn that whoever says, 'All these have I kept,' thereby convicts himself of understanding neither them nor himself.
Still he was not at rest, although he had, as he fancied, kept them all. His last question is a plaintive, honest acknowledgment of the hungry void within, which no round of outward obediences can ever fill. He knows that he has not the inner fountain springing up into eternal life. He is dimly aware of something wanting, whether in his obedience or no, at all events in his peace; and he is right in believing that the reason for that conscious void is something wanting in his conduct. But he will not learn what Christ has been trying to teach him, that he needs no new commandment, but a deeper understanding and keeping of the old. Hence his question, half a wail of a hungry heart, half petulant impatience with Christ's reiteration of obvious duties. There are multitudes of this kind in all ages, honestly wishing to lay hold of eternal life, able to point to virtuous conduct, anxious to know and do anything lacking, and yet painfully certain that something is wanting somewhere.
II. Now comes the sharp-pointed test, which pricks the brilliant bubble. Mark tells us that Jesus accompanied His word with one of those looks which searched a soul, and bore His love into it. 'If thou wouldest be perfect,' takes up the confession of something 'lacking,' and shows what that is. It is unnecessary to remark that this commandment to sell all and give to the poor is intended only for the individual case. No other would-be disciple was called upon to do so. It cannot be meant for others; for, if all were sellers, where would the buyers be? Nor need we do more than point out that the command of renunciation is only half of Christ's answer, the other being, 'Come, follow Me.' But we are not to slide easily over the precept with the comfortable thought that it was special treatment for a special case. The principle involved in it is medicine for all, and the only way of healing for any. This man was tied to earth by the cords of his wealth. They did not hinder him from keeping the commandments, for he had no temptations to murder, or adultery, or theft, or neglect of parents. But they did hinder him from giving his whole self up, and from regarding eternal life as the most precious of all things. Therefore for him there was no safety short of entire outward denuding himself of them; and, if he was in earnest out and out in his questions, here was a new thing for him to do. Others are hindered by other things, and they are called to abandon these. The one thing needful for entrance into life is at bottom self-surrender, and the casting away of all else for its sovereign sake. 'I do count them but dung' must be the language of every one who will win Christ. The hands must be emptied of treasures, and the heart swept clear of lesser loves, if He is to be grasped by our hands, and to dwell in our hearts. More of us than we are willing to believe are kept from entire surrender to Jesus Christ, by money and worldly possessions; and many professing Christians are kept shrivelled and weak and joyless because they love their wealth more than their Lord, and would think it madness to do as this man was bidden to do. When ballast is thrown out, the balloon shoots up. A general unlading of the 'thick clay' which weighs down the Christian life of England, would let thousands soar to heights which they will never reach as long as they love money and what it buys as much as they do. The letter of this commandment may be only applicable in a special case (though, perhaps, this one young man was not the only human being that ever needed this treatment), but the spirit is of universal application. No man enters into life who does not count all things but loss, and does not die to them all, that he may follow Christ.
