I. And first, then, let us consider the domestic or marriage yoke. What pen can portray the mental anguish, the moral misery, together with the ruinous consequences as to spiritual life and testimony, flowing from a Christian's marriage with an unconverted person? I suppose nothing can be more deplorable than the condition of one who discovers, when it is too late, that he has linked himself for life with one who cannot have a single thought or feeling in common with him. One desires to serve Christ; the other can only serve the devil: one breathes after the things of God; the other sighs for the things of this present world: the one earnestly seeks to mortify the flesh, with all its affections and desires; the other only seeks to minister to and gratify these very things. Like a sheep and a goat linked together, the sheep longs to feed on the green pasture in the field, while, on the other hand, the goat craves the brambles which grow in the ditch. The sad consequence is that both are starved. One _will_ not feed on the pasture, and the other _cannot_ feed upon the brambles, and thus neither gets what his nature craves, unless the goat, by superior strength, succeeds in forcing his unequally yoked companion to remain among the brambles, there to languish and die.
The moral of this is plain enough; and, moreover, it is, alas! of but too common occurrence. The goat generally succeeds in gaining his end. The worldly partner carries his or her point, in almost every instance. It will be found, almost without exception, that in cases of the unequal marriage-yoke, the poor Christian is the sufferer, as is evidenced by the bitter fruits of a bad conscience, a depressed heart, a gloomy spirit, and a desponding mind. A heavy price, surely, to pay for the gratification of some natural affection, or the attainment, it may be, of some paltry worldly advantage. In fact, a marriage of this kind is the death-knell of practical Christianity, and of progress in the divine life. It is morally impossible that any one can be an unfettered disciple of Christ with his neck in the marriage-yoke with an unbeliever. As well might a racer in the Olympic or Isthmæan games have expected to gain the crown of victory by attaching a heavy weight or dead body to his person. It is enough, surely, to have one dead body to sustain, without attaching another. There never was a true Christian yet who did not find that he had abundant work to do in endeavoring to grapple with the evils of _one_ heart, without going to burden himself with the evils of two; and, without doubt, the man who foolishly and disobediently marries an unconverted woman; or the woman who marries an unconverted man, is burdened with the combined evils of two hearts; and who is sufficient for these things? One can most fully count upon the grace of Christ for the subjugation of his own evil nature: but he certainly cannot count, in the same way, upon that grace in reference to the evil nature of his unequal yoke-fellow. If he have yoked himself ignorantly, the Lord will meet him personally, on the ground of full confession, with entire restoration of soul, but in the matter of his discipleship, he will never recover it.
Now, in considering the terribly evil consequences of the unequal marriage-yoke, it is mainly as bearing upon our discipleship that we are looking at them. I say "mainly" because our entire character and experience are deeply affected thereby. I very much question if any one can give a more effectual blow to his prosperity in the divine life than by assuming an unequal yoke. Indeed, the very fact of so doing proves that spiritual decline has already set in, with most alarming symptoms; but as to his discipleship and testimony, the lamp thereof may be regarded as all but gone out; or if it does give an occasional faint glimmer, it only serves to make manifest the awful gloom of his unhappy position, and the appalling consequences of being "unequally yoked together with an unbeliever."
Thus much as to the question of the unequal yoke in its influence upon the life, the character, the testimony, and the discipleship of the child of God.
