“And to the angel of the church in Sardis write, ‘These things says He who has the seven Spirits of God and the seven stars: ‘I know your works, that you have a name that you are alive, but you are dead. Be watchful, and strengthen the things which remain, that are ready to die, for I have not found your works perfect [finished or complete] before God. Remember therefore how you have received and heard; hold fast and repent. Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you.’” Revelation 3:1-3.
