We understand that you're seeking deliverance and protection from evil spirits, and we're here to pray with you and provide guidance. First, let's address your question about spirits leaving and returning. This can happen if there are open doors or legal rights that allow them to return. These can include unconfessed sin, unforgiveness, or involvement in activities that invite evil influences to enter a Christian believer.
As Jesus taught, "When the unclean spirit has gone out of a man, he walks through dry places, seeking rest, and finds none. Then he says, 'I will return to my house from which I came'; and when he comes, he finds it empty, swept, and put in order. Then he goes, and takes with himself seven other spirits more evil than he is, and they enter in and dwell there. The last state of that man becomes worse than the first" (Matthew 12:43-45 WEB).
To ensure lasting deliverance, it's crucial to close these open doors. Here's how you can pray:
"Father, in the name of Jesus Christ, I confess and repent of any sins that have allowed evil spirits to enter. I forgive those who have harmed me and renounce any involvement in activities that invite evil influences. Lord Jesus, you said 'And these signs shall follow them that believe; In my name shall they cast out devils;' (Mark 16:17 WEB), so I command these spirits to leave me and my territory permanently, in Jesus' name. I seal my home and my life with the blood of Jesus and ask you, Holy Spirit, to fill me and my territory with your presence. Thank you, Father, for your protection and deliverance, in Jesus' name, Amen."
Remember, 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 (Ephesians 6:12 WEB). So, put on the full armor of God (Ephesians 6:10-18 WEB) and stand firm in your faith.
