 Do you think that Jesus is afraid of the devil? Do you think that God panics when the enemy makes plans? Can you imagine a demon wrestling with the Holy Spirit and the Holy Spirit getting tired or calling for angelic backup? No? Well, don't you realize that he's given you the same authority? Luke 10.19 says, Behold, I give unto you power to tread on serpents and scorpions and over all the power of the enemy and nothing shall by any means hurt you. There is no spirit more powerful than the Holy Spirit and those who walk in the Holy Spirit walk in spiritual victory. When you rebuke the enemy, it's as if Jesus himself is rebuke the enemy. That's what it means to use his name. The only power the enemy has over you is the power you believe he has.
