Once you get born again, you are seated in the heavenly places in Christ Jesus, far above the devil and his agents, Eph 2:1-6. This is a spiritual position of authority over the devil and they are no longer supposed to oppress you.
Refuse to let them get you into bondage again by ignorance and fear, Isaiah 5:13, Rom 8:15. Never again feel threatened by them. You can cast them out and put a stop to their activities in all that has to do with you. Mark 16: 15 – 17.
I declare that every work of the devil against your life, your marriage, your career, your business be destroyed now in the name of Jesus
