Revelation 3

1And to the angel of the church in 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, and thou art dead.

2Be thou watchful, and establish the things that remain, which were ready to die: for I have found no works of thine perfected before my God.

3Remember therefore how thou hast received and didst hear; and keep it, and repent. If therefore thou shalt not watch, I will come as a thief, and thou shalt not know what hour I will come upon thee.

4But thou hast a few names in Sardis that did not defile their garments: and they shall walk with me in white; for they are worthy.

5He that overcometh shall thus be arrayed in white garments; and I will in no wise blot his name out of the book of life, and I will confess his name before my Father, and before his angels.
