In Isaiah, chapter sixty-one, verses ten through eleven, “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. For as the earth bringeth forth her bud, and as the garden causeth the things that are sown in it to spring forth; so the Lord GOD will cause righteousness and praise to spring forth before all the nations.
Those only shall be clothed with the garments of salvation hereafter, that are covered with the robe of Christ’s righteousness now, and by the sanctification of the Spirit have God’s image renewed upon them. These blessings shall spring forth for ages to come, as the fruits of the earth. So duly, so constantly, and with such advantage to mankind, will the Lord God cause righteousness and praise to spring forth. They shall spread far; the great salvation shall be published and proclaimed, to the ends of the earth. Let us be earnest in prayer, that the Lord God may cause that righteousness to spring forth among us, which constitutes the excellence and glory of the Christian profession.
After the return of Christ, all who are a part of His kingdom will rejoice. They will be clothed with “the garments of salvation” (they will be God’s redeemed) and “the robe of righteousness” (they will live by God’s standards). “Therefore, the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away,” in Isaiah fifty-one, verse eleven, which is known as a song.
