“Then I heard a loud voice saying in heaven, “Now salvation, and strength, and the kingdom of our God, and the power of His Christ have come, for the accuser of our brethren, who accused them before our God day and night, has been cast down. And they overcame him by the blood of the Lamb and by the word of their testimony, and they did not love their lives to the death.  Therefore rejoice, O heavens, and you who dwell in them! Woe to the inhabitants of the earth and the sea! For the devil has come down to you, having great wrath, because he knows that he has a short time.” Revelation 12: 10 – 12

“We do not understand as we should the great conflict going on between invisible agencies, the controversy between loyal and disloyal angels. Over every man, good and evil angels strive. This is no make-believe conflict. It is no mimic battle in which we are engaged. We have to meet most powerful adversaries, and it rests with us to determine which shall win. We are to find our strength where the early disciples found theirs.”(Evangelism 704.5)
