There is power in the blood of Jesus and there is power in the name of Jesus in our warfare against the devil. It is written, “And they overcame him (the devil) by the blood of the Lamb,” (Rev 12:11) and, “In My name they will cast out demons;” (Mark 16:17) The question is when do we use the blood of Jesus and when do we use the name of Jesus against the devil? Does the blood of Jesus and the name of Jesus have the same power over the devil that we can use either of them?
The blood of Jesus is the blood of redemption. We were the slaves of the devil. But by the blood of Jesus we were redeemed and set free from that enslavement. The apostle Peter wrote, “knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, but with the precious blood of Christ, as of a lamb without blemish and without spot.” (1 Pet 1:18-19) So, whenever we want to remind the devil that we are no longer his slave, that he cannot own our lives anymore, we use the blood of Jesus.
It is written, “For the Lord will pass through to strike the Egyptians; and when He sees the blood on the lintel and on the two doorposts, the Lord will pass over the door and not allow the destroyer to come into your houses to strike you.” (Exo 12:23) When the destroyer passed through the houses in the land of Egypt to strike every firstborn there, the Lord would not allow him to come to the houses of the children of Israel where the blood of the lamb was put on the lintel and on the two doorposts. The blood of the lamb is their protection from the destroyer. Likewise, the blood of Jesus is our protection from the devil who comes only to steal, to kill and destroy (John 10:10).
The name of Jesus is the name which is above every name that at the name of Jesus everyone will be subjected, every knee will bow. The apostle Paul wrote, “Therefore God also has highly exalted Him and given Him the name which is above every name, that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth,” (Phi 2:9-10) So whenever we want to make the devil be subjected to us, we use the name of Jesus. The seventy disciples who were sent by the Lord Jesus to preach the kingdom of God returned to Him with joy and said, “Lord, even the demons are subject to us in Your name.” (Luk 10:17)
It is written, “And Moses built an altar and called its name, The-Lord-Is-My- Banner; for he said, “Because the Lord has sworn: the Lord will have war with Amalek from generation to generation.” (Exo 17:15-16) Moses built an altar, calling its name Jehovah Nissi (The Lord is My Banner of Victory), because the Lord had sworn that He would make war with Amalek from generation to generation until the remembrance of Amalek is utterly blot out from under the heaven. In like manner, God has sworn that He will make war with the devil and his demons from generation to generation until their remembrance is utterly blot out from under the heaven and has given us the name of Jesus as a surety of victory over them.
The Lord Jesus said that one of the signs of those who believe in Him is they will cast out demons in His name (Mark 16:17). Casting out demons means commanding the demons to go out or go away. And, to cast out demons we use the name of Jesus because the name of Jesus carries God’s authority in heaven and on earth over all the demonic power. Demons are afraid in terror and are subject to that name.
What is the difference between the blood of Jesus and the name of Jesus as the weapon of warfare against the devil? The blood of Jesus is like the shield and the name of Jesus is like the sword. The shield is the weapon of defense or protection whereas the sword is the weapon of offense or attack. We use the blood of Jesus to protect us from the devil and we use the name of Jesus to resist the devil so that he will flee from us or to destroy his works.
The apostle Paul wrote, “Put on the whole armor of God, that you may be able to stand against the wiles of the devil.” (Eph 6:11) If we want to fully overcome the devil we must use both the blood of Jesus and the name of Jesus. The blood of Jesus is our shield so that the devil cannot hurt us by his weapons and the name of Jesus is our sword so that the devil cannot get close to us. Every time we use the blood of Jesus we are fully covered and protected from the devil. Every time we use the name of Jesus we hurt the devil and make him flee from us.
How do we use the blood of Jesus and the name of Jesus as the weapons of our warfare against the devil? By the spirit of faith. The apostle Paul wrote, “And since we have the same spirit of faith, according to what is written, “I believed and therefore I spoke,” we also believe and therefore speak.” (2 Cor 4:13) We proclaim the blood of Jesus over our lives to the devil and we rebuke the devil in the name of Jesus. We do not always have to speak with our mouth to use the blood of Jesus against the devil. Simply believing in our heart is often enough. However, we must always speak with our mouth to use the name of Jesus against the devil.
