“Fine linen are the righteous acts of the saints” (Revelation 19:8). Believers are clothed in Christ (Galatians 3), but in Revelation their clothing is their own righteous works.
Not everyone’s clothing is acceptable. Some dress in pride and violence (Psalm 73:6). At the center of Isaiah 59:6, Isaiah uses the word “works” three times: “they will not cover themselves with their works; their works are works of iniquity.” Their hands are full of violence.
These works are not linen garments, but spider’s webs, too fragile to use for clothing.
