Revelation 3:1-5

1“To the angel of the church in Sardis write the following: “This is the solemn pronouncement of the one who holds the seven spirits of God and the seven stars: ‘I know your deeds, that you have a reputation that you are alive, but in reality you are dead.

2Wake up then, and strengthen what remains that was about to die, because I have not found your deeds complete in the sight of my God.

3Therefore, remember what you received and heard, and obey it, and repent. If you do not wake up, I will come like a thief, and you will never know at what hour I will come against you.

4But you have a few individuals in Sardis who have not stained their clothes, and they will walk with me dressed in white, because they are worthy.

5The one who conquers will be dressed like them in white clothing, and I will never erase his name from the book of life, but will declare his name before my Father and before his angels.
