The following excerpt is taken from The Precious Blood of Jesus by Kenneth E. Hagin:

Pleading The Blood

…Jesus said, “In my Name they’ll cast out devils,” but did you ever stop to think that the power behind it is all
based on the blood? You must take the whole Word of God, not just part of it, to rightly divide the Word about
this truth.

When I came into Full Gospel circles, I remember they were always talking about “pleading the blood,” I didn’t
know what they were talking about until I began to examine the Scriptures on the subject. And I noticed one
thing in particular: What they did got results, and you can’t argue with success!

About this same time I read a testimony published in a Fall Gospel periodical. The author was a woman
missionary who had been left behind in a native village to take care for the church while the other missionaries
were away.

She went to the main part of that village and was examining some goods when a scorpion stung her. She was out
on the street when it fastened itself to her hand, so many of the people saw this.

She said, “I just shook it off and said, ‘In the Name of Jesus, I plead the blood!'”

(Did you ever stop to think that the Name of Jesus wouldn’t work if it weren’t for the blood? It all goes together.)

The missionary noticed that everyone was watching her, waiting for her to die, because no one had ever survived
the sting of that kind of scorpion. There was no antidote for it, either.

But the missionary just went her way, walking back toward the little mission church. The whole village followed,
still waiting for her to fall over dead. But nothing happened.

She went inside the church, and the villagers thronged after her. In fact, they couldn’t all fit in the church. Since
the church was full, the missionary decided to hold a service, even though it was the middle of the afternoon. She
was never affected by the scorpion’s sting.

She said, “In the Name of Jesus, I plead the blood against this!” You see, her understanding of the blood was a
little different from most people’s.

So I picked up that phrase, “In the Name of Jesus, I plead the blood’ from those Pentecostals, and all through
these years I’ve always pled the blood in the Name of Jesus. There’s power in the blood, glory to God! It’s worked
quite well for me, and it’ll work for you, too.

“And they overcame him [the devil] by [or because of] the blood of the Lamb, and by the word of their testimony
[confession]…”
And they have overcome (conquered) him by means of the blood of the Lamb and by the utterance of their
testimony, for they did not love and cling to life even when faced with death [holding their lives cheap till they
had to die for their witnessing]. (Rev. 12:11 AMP)

They defeated him through the blood of the Lamb and the bold word of their witness. They weren’t in love with
themselves; (Rev. 12: 11 The Message)
