Using the blood of Jesus as a talisman

Revelations 12:7-12 NLT

7.Then there was war in heaven. Michael and his angels fought against the dragon and his angels.

8. And the dragon lost the battle, and he and his angels were forced out of heaven

9. This great dragon—the ancient serpent
called the devil, or Satan, the one deceiving the whole world—was thrown down to the earth with all his angels.

10. Then I heard a loud voice shouting across the heavens,
“It has come at last—
salvation and power
and the Kingdom of our God,
and the authority of his Christ.
For the accuser of our brothers and sisters has been thrown down to earth—
the one who accuses them before our God day and night.

11. And they have defeated him by the blood of the Lamb and by their testimony.
And they did not love their lives so much
that they were afraid to die.

12. Therefore, rejoice, O heavens!
And you who live in the heavens, rejoice!
But terror will come on the earth and the sea, for the devil has come down to you in great anger, knowing that he has little time.”

Brethren, the first thing we need to know about the passage above is that the victory has already been won. Satan has already been defeated (v8)

A spiritual act inevitably becomes a physical reality with time.

How was Satan defeated?

Verse 11 tells us, (we) the brethren (the children of God) defeat Satan by the blood of the Lamb (which purchased for us, freedom from sin's bondage),  and by our testimony (the word of God in our mouth).
Our weapon against Satan is two-fold;

1.our embracing of Christ's sacrifice on the cross of calvary
2.our declaration of the Word of God over every circumstance we face in our daily encounters.

That twofold weapon has been there for over 2000 years, but will be useless in your life if you don't use it.

In verse 7, the angels defeated Satan. This victory is made manifest in our utilization of our weapon:- Embracing salvation through Christ and imbibing the Word of God in our hearts (for out of the abundance of the heart, the mouth speaks).

Dear brethren, shouting "Blood of Jesus!!!" is not the solution to our spiritual  problems. We need to realize the battle has already been won!

We enforce and manifest our victory by accepting Christ as Lord over our lives because He has paid the price to redeem us from sin and death, and we testify the word of God with our own mouth over every situation or circumstance we face in life. This is how we overcome.

Verse 12 says the devil has come down to earth in great anger, knowing he has little time.

Brethren, we need to stand firm today on the word of God against whatever the devil may throw in our path. Speak into your circumstance. Declare the word of God.

We are victorious!
