In connection with the light of heaven on the lusts of the heart, the Lord adds His word on the permission of divorce in Deut. 24. It is here the woman protected against hard-hearted man. Positive sin in violation of the marriage tie alone calls for divorce. Men abused the license beyond measure, as if the permission were a precept; and any vexation sufficed. But Jehovah hates putting away, as the last prophet testified to the Jews in their evil day.
In chap. 19 of this Gospel the question distinctly proposed to Him by the Pharisees, Is it lawful to put away one's wife for every cause? And He answered and said, Have ye not read that He that made from the beginning made them male and female, and said, For this cause shall a man leave his father and mother, and shall be united to his wife; and the two shall become one flesh? So that they are no more two, but one flesh. What therefore God joined together, let not man put asunder. They say to Him, Why then did Moses command to give a bill of divorce and to put away? He saith to them, Moses for your hardness of heart allowed you to put away your wives; but from the beginning it hath not been thus. But I say to you, Whosoever shall put away his wife, not for fornication, and shall marry another, committeth adultery, and he that marrieth one put away committeth adultery. His disciples say to Him, If the case of man be so with his wife, it is not good to marry. And He said to them, All cannot receive this word, but those to whom it hath been given.
Thus was the mind of God made clear. The indulgence of lust is incompatible with entering the kingdom of the heavens. The law forbade the act of adultery; the Lord condemns even the looking licentiously as adultery committed already in the heart. He insisted therefore on the most unsparing decision with all that gave occasion. Was it not better to pluck out the right eye or cut off the right hand, rather than the whole body be cast into hell? Here (as in all the chapters of the first Gospel before chapter 13 where He begins as the Sower), it is not seeking sinners in sovereign grace, but saints, as He enjoins on the twelve in chap. 10. “Into whatsoever city or village ye enter, inquire who in it is worthy” (ver. 11). So the beginning of the Sermon on the Mount (chap. 5) describes what spiritual characters suit the kingdom, as the end (chap. 7) declares that none shall enter but he that does the will of His Father that is in the heavens. Not even prophesying or miraculous powers, were it casting out demons through the Lord's name, could be a passport to the workers of lawlessness. Practical obedience of His words alone should stand. The rock here is spiritual reality. His word was incomparably more withering to self-righteousness than the law of Moses.
There is power of God given exceptionally to be above marriage, and live only to Christ here below. But, to far the most, marriage is God's order for man on earth. And the monkish rule with high pretension leads into horrible evasion, hypocrisy, and corruption even contrary to nature and abominable. God's mind is clear from the first; adultery alone justifies divorce.
Hence the necessity would be felt urgently and absolutely of receiving a new nature and an everlasting redemption in the Savior. No interpretation of our Lord's words here or elsewhere is more radically false than that He puts believers under the law as their rule of life. He is really condemning unbelievers and hypocrites far more stringently than the law did, and those sayings of the elders which took advantage of a legal permission for carnal indulgence and unfairness to a wife who through any cause became less attractive to her selfish husband. Such souls were inadmissible to the kingdom. Only the godly remnant are here contemplated, who abhor corruption as they do violence. The presence of Christ, not of the law given by Moses, was the suited moment for defining the character and conduct proper to the new thing He would set up. He was the standard of what pleased God, and must mark those who are His. “The law made nothing perfect” was a hard lesson for Jews; it seems quite as hard for those who inherit the traditions of fallen Christendom, and not less for Protestants than Papists.
To be content with being nobody in the world, and despised by its religion, is impossible to human nature; to be mourners as Christ was, feeling for God's will and majesty where lawlessness pervades; to be meek now, waiting for the glorious inheritance in God's time, instead of clamorous for our rights; to hunger and thirst after (not ease or wealth, or power or honor, but) righteousness, cannot be without partaking of a divine nature. Harder still was the actively gracious spirit of mercifulness, purity in heart, and peace-making according to God, with the persecutions which such righteousness entails, and especially such maintenance of Christ's name as effaces ours.
Our Lord accordingly singles out of the Decalogue the two great prohibitions of murder on the one hand and of adultery on the other. Assuredly He came not to make void the law or the prophets, but to give their fullness. He not only went farther than either, but declared that a righteousness surpassing that of the Scribes and Pharisees was indispensable for entering the kingdom of the heavens. He most pointedly sets His word with divine authority, so as to contrast what He laid down far beyond the claims of the law. In the case before us, as looking lustfully convicts of adultery before God, so whosoever put away his wife, save for cause of fornication, made her commit adultery, as well as him who married her. Thus He established a moral basis, not for a nation of mixed character, but fit for God's family and kingdom, which judged the heart's evil and allowed no concession to hardheartedness. And what can be plainer than on this later occasion (chap. 19) His going up to the beginning, long before the law, to God's instituted order and word in Gen. 2? There again His own word is full and final authority, for the Messiah was the Jehovah God of Israel. Whatever had been allowed by Moses, He is Mediator of a better covenant, which has been enacted on better promises. It is God speaking in Him who is Son: “But I say to you.”
Now, I appeal to your conscience, my reader. Can you face the light of God, which our Lord is, on these evils of man's fallen nature? Are you not utterly convicted by every saying of His, who is the Judge of living and dead? And if such be the truth, O spread it out, and yourself as verily guilty before God. Presume no more to stand on your own foundation. You are lost: own it truly and humbly and in earnest. The Lord Jesus is not Judge only; He is the real and the only and the present Savior of the lost. But you must be in the truth of your guilt in God's sight, if He is to act toward you in the truth of His salvation. That is repentance toward God; this is faith toward our Lord Jesus Christ.
There is for faith the blood of Jesus that cleanses from all, from every, sin. There is also life in Him, the Son, for every believer in Him. The one is as indispensable as the other. That life is the spring of the new nature which produces every good fruit and detests every evil work, word, and feeling; and now that one rests on His work of redemption, the Holy Ghost is given as divine power to strengthen the new man and mortify the old. It is true, that dependence on Christ, abiding in Him, is needed all the way through, and His words to abide in one, and prayer suitably and with confidence in divine love. But this is just practical Christianity so far; and we are sanctified by the Spirit, not to independence which is sin, but to obedience, the same blessed filial obedience as Christ's, our blessed Lord.
