What did Isaiah 61 show about Adam and Eve and Isaiah?
Isaiah 61:10 shows God clothing a person with the garments of salvation and covering them. This illustrates what Adam and Eve experienced, even as Isaiah did: an imputed, covering clothing of God's righteousness. Salvation there means God bringing someone out of destitution and covering them, not human self-righteousness.
Les explains that Isaiah 61:10 sets forth beautifully what Adam and Eve experienced, even as Isaiah did—an imputed, covering clothing of God's righteousness. In the verse, Isaiah rejoices because God has clothed him with the garments of salvation and covered him. Les emphasizes that salvation has always meant the same thing: bringing somebody out of a destitute place. He illustrates this with a man about to go bankrupt who is saved by a rich uncle's inheritance. He then connects this to Romans, where God has placed the righteousness of Christ unto all and upon all, so that it covers us.
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.
