There are three main questions on which the apostle here gives his inspired decision. The first decision is concerning the sanctity of the marriage-bond between two Christians. His verdict is given in the tenth verse: "Unto the married I command, yet not I, but the Lord, Let not the wife depart from her husband." He lays down this principle, that the union is an indissoluble one. Upon such a subject, Christian brethren, before a mixed congregation, it is manifestly evident that we can only speak in general terms. It will be sufficient to say that marriage is of all earthly unions almost the only one permitting of no change but that of death. It is that engagement in which man exerts his most awful and solemn power,--the power of responsibility which belongs to him as one that shall give account,--the power of abnegating the right to change,--the power of parting with his freedom,--the power of doing _that_ which in this world can never be reversed. And yet it is perhaps that relationship which is spoken of most frivolously, and entered into most carelessly and most wantonly. It is not an union merely between two creatures, it is an union between two spirits; and the intention of that bond is to perfect the nature of both, by supplementing their deficiencies with the force of contrast, giving to each sex those excellencies in which it is naturally deficient; to the one strength of character and firmness of moral will, to the other sympathy, meekness, tenderness. And just so solemn, and just so glorious as these ends are for which the union was contemplated and intended, just so terrible are the consequences if it be perverted and abused. For there is no earthly relationship which has so much power to ennoble and to exalt. Very strong language does the apostle use in this chapter respecting it: "What knoweth thou, O wife, whether thou shalt _save_ thy husband? or how knowest thou, O man, whether thou shalt save thy wife?" The very power of _saving_ belongs to this relationship. And on the other hand, there is no earthly relationship which has so much power to wreck and ruin the soul. For there are two rocks in this world of ours on which the soul must either anchor or be wrecked. The one is God; the other is the sex opposite to itself. The one is the "Rock of Ages," on which if the human soul anchors it lives the blessed life of faith; against which if the soul be dashed and broken, there ensues the wreck of Atheism--the worst ruin of the soul. The other rock is of another character. Blessed is the man, blessed is the woman whose life-experience has taught a confiding belief in the excellencies of the sex opposite to their own--a blessedness second only to the blessedness of salvation. And the ruin in the other case is second only to the ruin of everlasting perdition--the same wreck and ruin of the soul.
