Revelation 3:1-6 - The Letter To The Church In Sardis
1 And to the angel of the church at Sardis write, These things saith he that hath the seven spirits of God, and the seven stars, I know thy works, that thou hast a name that thou livest, but art dead. 2 Be watchful, and strengthen the things which remain, which are ready to die; for I have not found thy works compleat before my God. 3 Remember therefore how thou hast received and heard, and hold fast and repent. If thou watch not, I will come as a thief, and thou shalt not know at what hour I will come upon thee. 4 Yet thou hast a few names in Sardis, who have not defiled their garments; and they shall walk with me in white: they are worthy. 5 He that overcometh, he shall be cloathed in white raiment, and I will not blot his name out of the book of life, and I will confess his name, before my Father and before his angels.
6 He that hath an ear, let him hear what the Spirit saith to the churches.
