...But you need to walk in the light as Christ is in the light in order for the blood of Jesus to continue to cleanse you. How so? It is what 1 John 1:7 says.
"But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin." (1 John 1:7).
Also, we understand from Revelation 3:5 that he that overcomes shall be clothed in white clothing, too. What does Scripture say about this?
Revelation 19:8 says,
"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."
Here in this verse we see that the fine linen that is on the saints represents the
righteousness of the saints.
What is one way the Bible describes righteousness?
"Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous" (1 John 3:7).
So doing righteousness makes one righteous according to John.
Now, why is it important to know that the "bride" (Revelation 19:7) has on fine linen that represents the righteousness of the saints? (Revelation 19:8). Well, the Parable of the Wedding Banquet tells us that those who do not have on a wedding garment (Which is a picture of the righteousness of the saints) will be cast into outer darkness where there will be weeping and gnashing of teeth.
12 "And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless.
13 Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness, there shall be weeping and gnashing of teeth." (Matthew 22:12-13).
Gnashing of teeth is what wolves do.
