They say it is not by our doing and our power that the devil is defeated but the blood of Christ and the holy spirit. Did you know that exorcism is a real thing? did you also know that scripture is quoted over the possessed over and over again but at least 80% of the exorcism end up failing and worse in the death of the person?You will never beat the devil with song lyrics or analogies about what you think scripture might say.
This is because scripture alone is not enough you have to have the spirit and only by the spirits leading do you have any authority.
Even I have been physically attacked by a demon but it had to do as I said I didn't even know I had authority, another time I was attacked by another demon and all I knew to do was to say the name Jesus but the demon didn't want me to it was like my tongue was tied and I struggled to say his name but finally when I was able to say his name it had no choice but to leave.
Why was I able to do these things when so many exorcists would use scripture yet fail? because I understood and knew the power in his word because I knew his voice and did as the spirit lead me to do. I didn't think about the scriptures I didn't think to say his name I just knew because my spirit inside me told me so.
