Message to Sardis

1"To the angel of the church in Sardis write:
He who has the seven Spirits of God and the seven stars, says this: 'I know your deeds, that you have a name that you are alive, but you are dead.2'Wake up, and strengthen the things that remain, which were about to die; for I have not found your deeds completed in the sight of My God.3'So remember what you have received and heard; and keep it, and repent. Therefore if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.4'But you have a few people in Sardis who have not soiled their garments; and they will walk with Me in white, for they are worthy.5'He who overcomes will thus be clothed in white garments; and I will not erase his name from the book of life, and I will confess his name before My Father and before His angels.6'He who has an ear, let him hear what the Spirit says to the churches.'
