Revelation 3:1-5

1"And to the angel of the church in Sardis write: 'The words of him who has the seven spirits of God and the seven stars. "'I know your works. You have the reputation of being alive, but you are dead.

2Wake up, and strengthen what remains and is about to die, for I have not found your works complete in the sight of my God.

3Remember, then, what you received and heard. Keep it, and repent. If you will not wake up, I will come like a thief, and you will not know at what hour I will come against you.

4Yet you have still a few names in Sardis, people who have not soiled their garments, and they will walk with me in white, for they are worthy.

5The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels.
