Rev 3:1-6,14-22
I, John, heard the Lord saying to me, “Write to the angel of the church in Sardis and say, ‘Here is the message of the one who holds the seven spirits of God and the seven stars: I know about your behaviour: how you are reputed to be alive and yet are dead.
Wake up; put some resolve into what little vigour you have left: it is dying fast. So far I have failed to notice anything in your behaviour that my God could possibly call perfect; remember how you first heard the message. Hold on to that. Repent! If you do not wake up, I shall come to you like a thief, and you will have no idea at what hour I shall come upon you. There are a few in Sardis, it is true, who have kept their robes unstained, and they are fit to come with me, dressed in white.
