Revelation 3:1-3

21st Century King James Version

3 “And unto 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, and that thou hast a name that thou livest, but thou art dead.

² Be watchful and strengthen the things which remain, that are ready to die, for I have not found thy works perfect before God.

³ Remember therefore how thou hast received and heard; and hold fast and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
