I believe that the Lord Jesus has all authority in heaven and on earth, and He is head over all rule and authority. I am complete in Him. I believe that Satan and his demons are subject to me in Christ, since I am a member of Christ's body. Therefore, I obey the command to submit to God, and resist the devil, and I command Satan in the name of Jesus Christ to leave my presence!
This comes from Neil Anderson's book, "The Bondage Breaker." I cannot read it without weeping. Please pray for me and any spiritual attacks I am going through!
