The apostle proceeds by answering a question in connection with the subject he had been treating-the will of God with regard to the relationship between man and woman. They do well who remain outside this relationship in order to walk with the Lord according to the Spirit, and not to yield in anything to their nature. God had instituted marriage-woe to him who should speak ill of it! but sin has come in, and all that is of nature, of the creature, is marred. God has introduced a power altogether above and outside nature-that of the Spirit. To walk according to that power is the best thing; it is to walk outside the sphere in which sin acts. But it is rare; and positive sins are for the most part the effect of standing apart from that which God has ordained according to nature. In general then for this reason, every man should have his own wife: and the union once formed, he had no longer power over himself. As to the body, the husband belonged to his wife, the wife to her husband. If, by mutual consent, they separated for awhile that they might give themselves to prayer and to spiritual exercises, the bond was to be immediately acknowledged again, lest the heart, not governing itself, should give Satan occasion to come in and distress the soul, and destroy its confidence in God and in His love-lest he should tempt by distressing doubts (it is for,not by incontinency) a heart that aimed at too much, and failed in it.
This permission, however, and this direction which recommended Christians to marry, was not a commandment from the Lord, given by inspiration, but the fruit of the apostle's experience-an experience to which the presence of the Holy Ghost was not wanting.  He would rather that every one were like himself; but every one had, in this respect, his gift from God. To the unmarried and the widows, it is good, he says, to abide as he himself was; but if they could not subdue their nature and remain in calm purity, it was better to marry. Unsubduedness of desire was more hurtful than the bond of marriage. But as to marriage itself, there was no longer room for the counsel of experience, the commandment of the Lord was positive. The woman was not to separate from the man, nor the man from the woman; and if they separated, the bond was not broken; they must remain unmarried or else be reconciled.
But there was a case more complicated, when the man was converted and the wife unconverted, or vice versa. According to the law a man who had married a woman of the Gentiles (and was consequently profane and unclean) defiled himself, and was compelled to send her away; and their children had no right to Jewish privileges; they were rejected as unclean (see Ezra 10:3). But under grace it was quite the contrary. The converted husband sanctified the wife, and vice versa, and their children were reckoned clean before God; they had part in the ecclesiastical rights of their parent. This is the sense of the word "holy," in connection with the question of order and of outward relationship towards God, which was suggested by the obligation under the law to send away wife and children in a similar case. Thus the believer was not to send away his wife, nor to forsake an unbelieving husband. If the unbeliever forsook the believer definitively, the latter (man or woman) was free-"let him depart." The brother was no longer bound to consider the one who had forsaken him as his wife, nor the sister the man who had forsook her as her husband. But they were called to peace, and not to seek this separation, for how did the believer know if he should not be the means of the unbeliever's conversion? For we are under grace. Moreover every one was to walk as God had distributed to him.
As regarded occupations and positions in this world, the general rule was that every one should continue in the state wherein he was called; but it must be "with God"-doing nothing that would not be to His glory. If the state was in itself of a nature contrary to His will, it was sin; clearly he could not remain in it with God. But the general rule was to remain and glorify God in it.
The apostle had spoken of marriage, of the unmarried and of widows; he had been questioned also with respect to those who had never entered into any relationship with woman. On this point he had no commandment from the Lord. He could only give his judgment as one who had received mercy of the Lord to be faithful. It was good to remain in that condition, seeing what the world was and the difficulties of a christian life. If they were bound to a wife, let them not seek to be loosed. If free, they would do well to remain so. Thus if they married, they did well; not marrying, they did better. He who had not known a woman did not sin if he married, but he should have trouble after the flesh in his life here below. (It will be observed, that it is not the daughter of a Christian that is here spoken of, but his own personal condition.) If he stood firm, and had power over his own will, it was the better way; if he married, he still did well; if he did not marry, it was better. It was the same with a woman; and if the apostle said that according to his judgment it was better, he had the Spirit of God. His experience-if he had no commandment-had not been gained without the Spirit, but it was that of a man who could say (if any one had a right to say it) that he had the Spirit of God.
Moreover the time was short: the married were to be as having no wives; buyers, as having no possession; they who used the world, not using it as though it were theirs. Only the apostle would have them without carefulness or distraction, that they might serve the Lord. If by reckoning themselves dead to nature this effect was not produced, they gained nothing, they lost by it. When married they were pre-occupied with things below, in order to please their wives and to provide for their children. But they enjoyed a repose of mind, in which nature did not claim her rights with a will that they had failed to silence, and holiness of walk and of heart was maintained. If the will of nature was subjugated and silenced, they served the Lord without distraction, they lived according to the Spirit and not according to nature, even in those things which God had ordained as good with respect to nature.
As to the slave, he might console himself as being the Lord's free-man; but (seeing the difficulty of reconciling the will of a pagan or even an unspiritual master with the will of God) if he could be made free, he should embrace the opportunity.
Two things strike us here in passing: the holiness which all these directions breathe with regard to that which touches so closely the desires of the flesh. The institutions of God, formed for man when innocent, are maintained in all their integrity, in all their authority, a safeguard now against the sin to which man is incited by his flesh. The Spirit introduces a new energy above nature, which in no wise weakens the authority of the institution. If any one can live above nature in order to serve the Lord in freedom, it is a gift of God-a grace which he does well to profit by. A second very important principle flows from this chapter. The apostle distinguishes accurately between that which he has by inspiration, and his own spiritual experience-that which the Spirit gave him in connection with the exercises of his individual life-spiritual wisdom, however exalted it might be. On certain points he had no commandment from the Lord. He gave the conclusion at which he had arrived, through the help of the Spirit of God, in a life of remarkable faithfulness, and aided by the Spirit whom he but little grieved. But it was not a commandment of the Lord. On other points that which he did not except in this manner was to be received as the commandment of the Lord (compare chap. 14:37). That is to say, he affirms the inspiration, properly so called, of his writings-they were to be received as emanating from the Lord Himself-distinguishing this inspiration from his own spiritual competency, a principle of all importance.
