We understand your concern and desire to be free from any evil influence, but we must address this from a biblical perspective. Firstly, it's important to note that Beelzebub, or any other demon, cannot possess a true believer in Christ, for we are temples of the Holy Spirit. As it is written in 1 Corinthians 6:19-20 WEB, "Or don’t you know that your body is a temple of the Holy Spirit which is in you, which you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God’s."
We must also point out that your request does not mention the name of Jesus Christ. It is only through His name that we have access to God and can be saved. As it is written in Acts 4:12 WEB, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
If you are truly born again, Beelzebub cannot be in you. However, if you are not, we urge you to turn to Jesus Christ in faith and repentance. If you are experiencing spiritual disturbances, it may be due to sin in your life, or influence from evil spirits because you are a non believer. In either case, the solution is to turn to Jesus Christ, confessing your sins and seeking His forgiveness and Lordship.
As for your cat or any other pet, we should remember that God cares for all His creation, but pets do not have spirits like humans do. They are not subject to spiritual possession like one might imagine in their own body. They are subject to the results of good and evil by proximity to the behavior of their owners or other surroundings. They are certainly valuable to God but not like us. They will not go to heaven or hell. It is all a mystery.
If you have a pet that may be experiencing disturbances, it is important to address the pets surroundings, such as removing objects related to evil, possibly providing Christian music, or anything that promotes God. It might help. Please carefully consider the above. If you agree, then we should pray together in the name of Jesus.
Let us pray:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, seeking Your divine protection and deliverance for this individual and their pet. We stand set free by truth and righteousness that we have by faith through Jesus Christ our Lord. We stand upon Your promise of Psalm 91 which speaks of our protection in You.
Lord, if this person is not truly born again, we pray that they would turn to Jesus Christ in repentance and faith, receiving Your forgiveness and salvation. If they are truly born again, we pray that You would help them walk in the light, with knowledge of the truth. Equipping them with skills to discern any sin in their lives, helping them to turn away from anything not pleasing to You and honor You in all they do.
Help us to remember James 4:7-8 where it is written, "Be subject therefore to God. But resist the devil, and he will flee from you. Draw near to God, and he will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded."
Lord, we ask for Your divine protection for their pet as well, keeping us from harm by obstacles presented by evil.
In Jesus' name, we pray. Amen.
