Hope you’re encouraged by this imagery as I was!
The third incomparable grace of faith is this: that it unites the soul to Christ, as the wife to the husband, by which mystery, as the Apostle teaches, Christ and the soul are made one flesh. Now if they are one flesh… then it follows that all they have becomes theirs in common, as well good things as evil things; so that whatsoever Christ possesses, that the believing soul may take to itself and boast of as its own, and whatever belongs to the soul, that Christ claims as His.
For, since Christ is God and man, and is such a Person as neither has sinned, nor dies, nor is condemned, nay, cannot sin, die, or be condemned, and since His righteousness, life and salvation and invincible, eternal, and almighty, — when I say, such a Person, by the wedding-ring of faith, takes a share in the sins, death and hell of His wife, nay, makes them His own and deals with them no otherwise than as if they were His, and as if He Himself had sinned; and when He suffers, dies, and descends to hell, that He may overcome all things, and since sin, death, and hell cannot swallow Him up, them must needs be swallowed up by Him in stupendous conflict. For His righteousness rises above the sins of all men; His life is more powerful than all death; His salvation is more unconquerable than all hell.
Who then can value highly enough these royal nuptials? Who can comprehend the riches of the glory of this grace? Christ, that rich and pious Husband, takes as a wife a needy and impious harlot, redeeming her from all her evils and supplying her with all His good things. It is impossible now that her sins should destroy her, since they have been laid upon Christ and swallowed up in Him, and since she has in her Husband Christ a righteousness which she may claim as her own, and which she can set up with confidence against all her sins, against death and hell, saying, “If I have sinned, my Christ, in whom I believe, has not sinned; all mine is His, and all His is mine,” as it is written, “My beloved is mine, and I am His”. This is what Paul says: “Thanks be to God, which giveth us the victory through our Lord Jesus Christ,” victory over sin and death, as he says, “The sting of death is sin, and the strength of sin is the law”.
