In our study of the Lamb there were three verses in the book of Revelation that made reference to the blood of the Lamb. In 5:9 the heavenly chorus declared, “You are worthy…because you were slain, and with your blood you purchased men for God.” Then in 7:14 it describes tribulation saints as those who “have washed their robes and made them white in the blood of the Lamb.” Again in 12:11 it says, “They overcame him (that is, the Devil) by the blood of the Lamb and by the word of their testimony.”
These verses emphasize three points: purchased by the blood, purified through the blood, and power in the blood. These points indicate what God provided for us so we can live under any circumstance for His glory.
Since we’re purchased, our only proper response in our relationship with God is full surrender and obedience to Him. We didn’t do anything, nor could we, to earn our privileged position of being His child.
The blood of the Lamb was the purchase price to buy us out of the slave market of sin. Once purchased, we’re to be purified and kept clean. Only the blood of the Lamb has the potency to cleanse sin’s stains from our lives.
All who thus commit themselves to God and seek His cleansing through confession, nevertheless find they’re continually under attack from the Devil. The only way to overcome him is claim the power of the blood of the Lamb and bear testimony that you’re relying on Christ’s victory on the cross.
