Courtney, we understand your distress and are here to support you in prayer and guidance. Let's begin by addressing the spiritual warfare you believe you're experiencing. The Bible tells us, "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places" (Ephesians 6:12, WEB).
Firstly, it's crucial to ensure you're protected by the authority of Jesus Christ. We noticed that your request does not mention His name. It's important to know that "there is no other name under heaven given among men by which we must be saved" (Acts 4:12, WEB). If you haven't already, we encourage you to accept Jesus Christ as your Lord and Savior, for it is through Him that we have access to God and can be saved from evil spirits.
Now, let's pray for your deliverance:
"Father, we come before You in the mighty name of Jesus. We plead the blood of Jesus over Courtney's life, her home, and her family. We bind and rebuke any evil spirits that may be causing pain, torture, bad luck, stress, carelessness, anxiety, and depression in her life. By the power of the Holy Spirit, we command these spirits to leave and never return. Lord, surround Courtney with Your angels to protect her from any further harm.
Father, we also pray for healing. Today, Courtney was attacked by a wasp and had a severe allergic reaction. Lord, touch her body and heal her from this reaction and any other physical ailments.
Lord, we lift up Courtney's relationship with her grandmother. We pray for understanding, patience, and love between them. Guide Courtney's steps and help her to walk in a manner that pleases You. Give her the strength to endure any trials and the faith to believe in Your deliverance.
In Jesus' name, we pray. Amen."
Courtney, continue to seek the Lord and His Word. Put on the full armor of God daily (Ephesians 6:13-18), and resist the devil (James 4:7). Remember, "God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make a way of escape, that you may be able to endure it" (1 Corinthians 10:13, WEB).
Lastly, consider finding a strong, Bible-believing church for fellowship and support. It's important to have a spiritual family to help you grow in Christ and stand with you in times of trial.
Amen, Sweaxulira! Keep agreeing in prayer. "If two of you agree on earth about anything they ask, it will be done for them by my Father in heaven." (Matt 18:19) God hears our united prayers. "Rejoice always, pray continually, give thanks in all circumstances; for this is God’s will for you in Christ Jesus." (1 Thess 5:16-18) In Jesus' name!
