To the Church in Sardis
3"To the angel of the church in Sardis write:
These are the words of him who holds the seven spirits of God and the seven stars. I know your deeds; you have a reputation of being alive, but you are dead. 2 Wake up! Strengthen what remains and is about to die, for I have not found your deeds complete in the sight of my God. 3 Remember, therefore, what you have received and heard; obey it, and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you.
4 Yet you have a few people in Sardis who have not soiled their clothes. They will walk with me, dressed in white, for they are worthy. 5 He who overcomes will, like them, be dressed in white. I will never blot out his name from the book of life, but will acknowledge his name before my Father and his angels. 6 He who has an ear, let him hear what the Spirit says to the churches."
