Thematic Bible: The reward for not being aware

And to the messenger of the assembly in Sardis write: These things saith he who is having the Seven Spirits of God, and the seven stars: I have known thy works, and that thou hast the name that thou dost live, and thou art dead; become watching, and strengthen the rest of the things that are about to die, for I have not found thy works fulfilled before God. 'Remember, then, how thou hast received, and heard, and be keeping, and reform: if, then, thou mayest not watch, I will come upon thee as a thief, and thou mayest not know what hour I will come upon thee.
