"And they overcame him by the blood of the Lamb, and by the word of their testimony" (Rev. 12:11).
Because Satan is the god of this world (2 Cor. 4:4), he will try to exercise authority over you in this life. He will try to dominate you. He will try to keep you from walking in your redemptive rights.
But you can overcome the devil every time, no matter what the test. You can overcome him because of the blood of the Lamb and the word of your testimony!
You simply have to know what the blood has bought for you: deliverance from the power (authority) of darkness (Satan), and translation (by virtue of the New Birth) into the kingdom of light. Then you have to add your testimony to that knowledge.
Stand your ground. Confess what the blood of the Lamb has wrought. Thank God, there is power in the blood! But the power in the blood won't just work automatically - you have to add your testimony to it.
Confession: I am an overcomer. I overcome the devil in every confrontation; he never overcomes me. I overcome him by the blood of the Lamb, and by the word of my testimony.
