2. Illustrations from the Moral Law (vv. 21-48).

The selection of illustrative instances is made with consummate skill. Our Lord, avoiding that which is specially Jewish in its interest, treats of matters that are of world-wide importance. He deals with the broadest principles of righteousness as adapted to the universal conscience of mankind, starting at the lowest point of mere earthly morality and rising to the very highest development of Christian character, thus leading up to the magnificent conclusion: "Be ye therefore perfect, even as your Father which is in heaven is perfect."

He begins with the crime which the natural conscience most strongly and instinctively condemns, the crime of murder; and shows that the scribes and Pharisees, 74 and those who had been like them in bygone days, really destroyed the sixth commandment by limiting its range to the muscles, so that, if there were no actual killing, the commandment was not broken; whereas its true sphere was the heart, the essence of the forbidden crime being found in unjustifiable anger, even though no word is uttered or muscle moved,—a view of the case which ought to have been suggested to the intelligent student of the law by such words as these: "Thou shalt not hate thy brother in thine heart" (Lev. xix. 17); or again: "Whoso killeth his neighbour ignorantly, whom he hated not in time past, ... is not worthy of death, inasmuch as he hated him not in time past" (Deut. xix. 4). Hatred in the heart, then, is murder. How searching! And how terribly severe the sentence! Even in its least aggravated form it is the same as that decreed against the actual shedding of blood. All the three sentences are death-penalties, only there are aggravations in the penalty where there are aggravations in the offence. Such is the Saviour's teaching on the great subject of sin. Yet there are those who imagine that the Sermon on the Mount is all the gospel they need!

The two practical applications which follow press the searching subject home. The one has reference to the Throne of Grace, and teaches that all offences against a brother must be put away before approaching it. The other has reference to the Throne of Judgment, and teaches by a familiar illustration drawn from common experience in the courts of Palestine that it is an awful thing to think of standing there with the memory of a single angry feeling that had not been forgiven and utterly removed (v. 26).

The crime of adultery furnishes the next illustration; 75 and He deals with it on the same lofty principles and with the same terrible severity. He shows that this crime, too, is of the heart—that even a wanton look is a commission of it; and again follows up His searching exposition by a twofold practical application, first showing that personal purity must be maintained at any cost (vv. 29, 30), and then guarding the sacredness of home, by that exaltation of the marriage bond which has secured the emancipation of woman and her elevation to her proper sphere, and kept in check those frightful evils which are ever threatening to defile the pure and sacred spring from which society derives its life and sustenance (vv. 31, 32).

Next comes the crime of perjury—a compound sin, which breaks at the same time two commandments of the Decalogue, the third and the ninth. Here, again, our Lord shows that, if only due homage is paid in the heart to reverence and to truth, all swearing is superseded. Let a man habitually live in the fear of the Lord all the day long, and "his word is as good as his oath"—he will always speak the truth, and will be incapable of taking the name of the Lord in vain. It is of course to be remembered that these are the laws of the kingdom of Christ; not laws meant for the kingdoms of this world, which have to do with men of all sorts, but for a kingdom made up of those who hunger and thirst after righteousness, who seek and find purity of heart. This passage accordingly has no bearing on the procedure of secular courts of justice. But, though the use of oaths may still be a necessity in the world, in the kingdom of heaven they have no place. The simple "Yea, yea," "Nay, nay," is quite enough where there is truth in the 76 inward parts and the fear of God before the eyes; and the feeling of reverence, not only for God Himself but for all the works of His hands, will effectually prevent the most distant approach to profanity.

The sin of revenge furnishes the next illustration. The Pharisaic perversion of the old law actually sanctioned private revenge, on the ground of a statute intended for the guidance of the courts of justice, and given for the sake of curbing the revengeful spirit which without it would lead a prosecutor to demand that his enemy should suffer more than he had inflicted. In this way they really destroyed that part of the Mosaic legislation, whereas He fulfilled it by developing still further,—bringing, in fact, to perfection,—that spirit of humanity which had dictated the law at the first. The true spirit of the Mosaic legislation was to discourage private revenge by assigning such cases to the courts, and curbing it still further by the limitation of the penalty imposed. Was not this spirit most nobly fulfilled, carried to its highest development, when the Saviour laid it down as the law of His kingdom that our revenge is to be the returning of good for evil?

The four practical illustrations (vv. 39-42) have been a source of difficulty, but only to those who forget that our Saviour is all the while warning against "the letter that killeth," and showing the need of catching "the spirit" of a commandment which "giveth life" to it. To deal with these illustrations according to the letter, as telling us exactly what to do in particular cases, is not to fulfil but to destroy the Saviour's words. The great thing, therefore, is to catch their spirit; then they will be found of use, not for so many specified cases, but for all cases whatever. 77 As an illustration of the difficulties to which we refer, mention may be made of the prejudice against the passage which suggests the turning of the other cheek, on the ground that it encourages a craven spirit. Take it as a definite command, and this would be in many cases the result. It would be the result wherever fear or pusillanimity was the motive. But where is there in all this passage the least trace of fear or pusillanimity? It is all love and magnanimity. It is the very antipodes of the craven spirit. It is the heroism of self-denying love!

The last illustration cuts at the root of all sin and crime, the tap-root of selfishness. The scribes and Pharisees had made use of those regulations, most needful at the time, which separated Israel from other nations, as an excuse for restricting the range of love to those prepared to render an equivalent. Thus that wonderful statute of the old legislation, "Thou shalt love thy neighbour as thyself," was actually made a minister to selfishness; so that, instead of leading them to a life above the world, it left them not a whit better than the lowest and most selfish of the people. "If ye love them which love you, what reward have ye? Do not even the publicans the same?" Thus was the noble "royal law according to the Scripture" destroyed by the petty quibbling use of the word "neighbour." Our Lord fulfilled it by giving to the word neighbour its proper meaning, its widest extent, including even those who have wronged us in thought or word or deed, "I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you."

How lofty, how far beyond the reach of the natural 78 man!—but not impossible, or it would not have been demanded. It is one of the things of the kingdom concerning which the assurance is given later on: "Ask, and ye shall receive; seek, and ye shall find." Still, the Master knows full well that it is no small demand He is making of poor human nature. So at this point He leads our thoughts upward to our Father in heaven, suggesting in that relationship the possibility of its attainment (for why should not a child be like its father?) and the only example possible, for this was a range of righteousness beyond the reach of all that had gone before—He Himself as the Son of the Father would later set it forth before the eyes of men in all its lustre. But that time is yet to come, and meantime He can only point upward to the Highest, and urge them to this loftiest height of righteousness by the tender plea, "That ye may be the children of your Father which is in heaven: for He maketh His sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust."

How beautiful and expressive are these symbols from nature, and how encouraging the interpretation of nature His use of them suggests! And what shall we say of their suggestiveness in the higher sphere of the spirit? Already the Sun of Righteousness is rising with healing in His wings; and in due time the rain of the Spirit will fall in fulness of blessing; so shall His disciples receive all that is needful to raise them to the very highest in character and conduct, in beatitude and righteousness; and accordingly their Master may well finish His whole exposition of the morals of the kingdom with the stirring, stimulating call, "Be ye therefore perfect, even as your Father which is in heaven is perfect."
