Revelation 3:2

1 “To the angel of the church in Sardis write: These are the words of the One who holds the seven Spirits of God and the seven stars. I know your deeds; you have a reputation for being alive, yet you are dead.

Wake up and strengthen what remains, which was about to die; for I have found your deeds incomplete in the sight of My God.

3 Remember, then, what you have received and heard. Keep it and repent. If you do not wake up, I will come like a thief, and you will not know the hour when I will come upon you.

4 But you do have a few people in Sardis who have not soiled their garments, and because they are worthy, they will walk with Me in white.

Do read the surrounding verses too, because the context often says more than a single verse.
