We don't fight flesh and blood.

"Father, I come to You in the Name of Jesus as Your blood-bought child. Being faced with demonic opposition, I want to be sure I have closed all legal access the enemy may have in this matter. Forgive me of all sin that would have opened the door to this attack. Bring to mind anything I need to surrender so this door would be shut. I ask that You cleanse me from all defilement of flesh and spirit. I fully submit myself to You and expect my enemies to flee. I put on the whole armor of God as You have instructed and having done all, I pray in the spirit and STAND. I refuse to hate or be in strife with any people who are involved in this matter. Forgive me for speaking against any of them and I forgive them wherever they have wronged me. I choose to bless and not curse. You are mighty, Lord God, and I surrender this battle to You as I stand to see the salvation of the Lord. No weapon formed against me will prosper and every tongue that is raised in judgment against me will be shown to be in the wrong. Let my life and all I know and am responsible for be covered by the blood of Jesus that evil will pass me by as the Lord, my victorious warrior, is my portion!"

The Lord rebukes you, Satan! I have authority over you and any actions you have set in place against me. You were defeated at the cross and I remind you of that right now. Release me, my household, and all that I own in the Name of Jesus. GO, report your failure, and do not return.

"Finally, be strong in the Lord and in his mighty power. Put on the full armor of God, so that you can take your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand.  Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace.  In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God. And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people. "
