Revelation 3:1-6 RHE

1 And to the angel of the church of Sardis write: These things saith he that hath the seven spirits of God and the seven stars: I know thy works, and that thou hast the name of being alive. And thou art dead.
2 Be watchful and strengthen the things that remain, which are ready to die. For I find not thy works full before my God.
3 Have in mind therefore in what manner thou hast received and heard: and observe and do penance: If then thou shalt not watch, I will come to thee as a thief: and thou shalt not know at what hour I will come to thee.
4 But thou hast a few names in Sardis which have not defiled their garments: and they shall walk with me in white, because they are worthy.
5 He that shall overcome shall thus be clothed in white garments: and I will not blot out 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.
