John Gill: Christ's Righteousness is the Wedding Garment

John Gill points to the righteousness of Christ as the garment for the wedding feast in Jesus' parable of Matthew 22:

[The wedding garment in Matthew 22:11 is] not good works, or a holy life and conversation, nor any particular grace of the Spirit, as faith, or charity, or humility, or repentance, or any other, nor the whole work of sanctification, nor the Holy Ghost, but the righteousness of Christ: for though good works are the outward conversation garments of believers, and these greatly become them and adorn the doctrine of Christ, yet they are imperfect, and have their spots, and need washing in the blood of Christ, and cannot in themselves recommend them to God; and though the Holy Spirit and his graces, his work of holiness upon the heart, make the saints all glorious within, yet not these, but the garment of Christ's righteousness, is their clothing of wrought gold, and raiment of needlework, in which they are brought into the king's presence: this, like a garment, is without them, and put upon them; and which covers and protects them, and beautifies and adorns them; and which may be called a wedding garment, because it is that, in which the elect of God were betrothed to Christ; in which they are made ready and prepared for him, as a bride adorned for her husband: and in which they will be introduced into his presence, and be by him presented, first to himself, and then to his Father, without spot, or wrinkle, or any such thing. This man had not on this garment, this robe of righteousness; it was not imputed to him; he had no knowledge of it; or if he had any, it was only a speculative one; he had no true faith in it; he had never put on Christ, as the Lord his righteousness; he had got into a church state without it, though there is no entrance into the kingdom of heaven but by it. (John Gill, Commentary on Matthew 22:11)
