Revelation 3:1-6

3:1 “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. 2 Wake 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. 3 Therefore, 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. 4 But 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. 5 The 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. 6 The one who has an ear had better hear what the Spirit says to the churches.’
