Where does the Bible say God clothes us with garments of righteousness?
The Bible says God clothes us with garments of righteousness in Isaiah chapter 61, where it declares, "Thou hath clothed me with the garments of righteousness." This is also illustrated in Genesis when God clothed Adam and Eve, and Paul confirms in Romans 3 that righteousness is imputed to all who believe.
Les explains that God clothing us with righteousness is pictured in Genesis, when He killed animals for Adam and Eve and clothed them, which was not just covering nakedness but clothing them with righteousness. He then points to Isaiah chapter 61, where the same statement appears: "Thou hath clothed me with the garments of righteousness." He also takes us to Romans chapter 3, where Paul says the same thing happens unto all that believe, and here in verse 10, with the heart man believes unto righteousness—an imputed thing, so God can actually clothe the believer with the righteousness of Christ.
I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels.
