Revelation 3:1-6 - The Letter To The Church In Sardis
1 And to the messenger of the church in Sardis write: Thus says he having the seven spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead: 2 Be watching, and make firm the remaining things, which are about to die: For I have not found thy works perfected before God. 3 Remember therefore how thou hast received, and heard, and do thou, and repent. If therefore thou watch not, I will come upon thee as a thief, and thou shalt not know what hour I shall come upon thee. 4 Thou hast a few names also in Sardis which stained not their garments; and they shall walk about with me in white things: for they are worthy. 5 He conquering, the same shall be surrounded in white garments; and I will not wipe out his name from the book of life, but I will acknowledge his name before my Father, and before his messengers.
6 He having ears, let him hear what the Spirit says to the churches.
