Revelation 12:10-11

10And I heard a great voice in heaven, saying,

Now is come the salvation, and the power, and the kingdom of our God, and the authority of his Christ: for the accuser of our brethren is cast down, who accuseth them before our God day and night. 11And they overcame him because of the blood of the Lamb, and because of the word of their testimony; and they loved not their life even unto death.
