“Pleading the blood” is actually a legal term. Think of it like a lawyer pleading his case before the judge. He presents evidence and facts to support his case. We have examples of this term in the Old Testament (1 Samuel 24:15; Psalm 43:1).
When the accuser says we’re guilty, our plea before God, the Righteous Judge, is the blood of Jesus. It changed everything. The blood of Jesus established a new and better covenant between us and a holy God (Hebrews 8:6-7, 9:11-14, 22, 12:24). The blood is our defense. It declares we are not guilty but free from all penalty of sin. The blood also gives us the authority and dominion to resist Satan and put him out of all the affairs of our lives and our families’ lives.
Because of Jesus’ sacrifice at Calvary, the devil has no legal right to interfere in our lives anymore. He says we’re guilty; we “plead the blood!” (James 4:7; 1 John 3:8; Luke 10:19). We have every right and provision to walk in victory through the precious blood of the Lamb.
Every day you have the right to exercise that authority by pleading what the blood of Jesus has done for you. Refuse to give the enemy even one small inch of territory. Satan is a defeated foe and through the precious blood of Jesus we are victorious!
