Revelation 12:10-11

10And I heard a great voice in the heaven saying, Now is come the salvation and the power and the kingdom of our 1God, and the authority of his Christ; for the accuser of our brethren has been cast out, who accused them before our 2God day and night:

11and they have overcome him by reason of the blood of the Lamb, and by reason of the word of their testimony, and have not loved their life even unto death.
