Revelation 3:1-6 - The Letter To The Church In Sardis
1 And to the angel of the church in Sardis write, These things says he that has the seven spirits of God and the seven stars, I know your works, that you have a name to live, and are dead. 2 Be watchful, confirm the rest who are about to die. For I have not found your works perfect before my God. 3 Remember therefore how you have received and heard, and watch, and change your minds. If therefore you do not watch, I will come as a thief, and you shall not know at what hour I will come upon you. 4 But you have a few names in Sardis who have not defiled their garments, and they shall walk with me in white, for they are worthy. 5 He that conquers shall be clothed in white robes, and I will not obliterate his name from the book of life, and I will confess his name before my Father and before his angels.
6 Let him that has an ear hear what the Spirit says to the churches.
