“And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.”
King James Version (KJV)
19:8 And it is given to her - By God. The bride is all holy men, the whole invisible church. To be arrayed in fine linen, white and clean - This is an emblem of the righteousness of the saints - Both of their justification and sanctification.
Re 19:8 To her was granted. By divine grace. That she should be arrayed in fine linen, clean and white. She must be arrayed in spotless white. For the fine linen is the righteousness of saints. What this white raiment is not left in doubt. It is woven by the pure and holy lives of the saints.
