We are truly sorry to hear about the struggles you and your parents are facing. In times like these, it's important to remember that God is our refuge and strength, a very present help in trouble (Psalm 46:1 WEB).
Firstly, it's crucial to pray in the name of Jesus Christ. It is only by His name that we have access to God the Father. As it is written, "In no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved!" (Acts 4:12 WEB).
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our beloved brother/sister and their parents. Lord, You promise that if we ask anything according to Your will, You hear us. And if we know that You hear us, whatever we ask, we know that we have the petitions that we have asked of You (1 John 5:14-15 WEB).
Father, we plead Your blood over their home and we bind and cast out any spirit of confusion, dementia, stubbornness, and disobedience that may be tormenting their father in Jesus' name. We pray for Your divine intervention, that You would heal his mind and body, and restore peace and order in their home.
Lord, we also lift up their mother, asking that You would grant her supernatural strength, patience, and endurance. Comfort her, Father, and wipe away her tears. Help her to respond in love and kindness, even in the face of trials.
Father, we pray for wisdom for their family, that they would know how to care for their father in a way that honors You. Guide them to the right resources and support they need. We also pray for their father's salvation, that he would come to know You personally.
Lord, we know that Your desire is for all to come to the knowledge of the truth and be saved (1 Timothy 2:3-4 WEB). We pray that through this trial, their family would draw closer to You, trusting in Your goodness and faithfulness.
In Jesus' name, we pray. Amen.
In this situation, it's also important to remember the exhortation in Ephesians 6:2-3 (WEB), "Honor your father and mother," which is the first commandment with a promise: "that it may be well with you, and you may live long on the earth." Even in difficult times, we are called to honor our parents with love, respect, and kindness.
Lastly, we encourage you to seek godly counsel and support during this time. The local church is a great place to start. There may be brothers and sisters in Christ who have gone through similar situations who can offer practical advice and encouragement.
Remember, "Don't be anxious for anything, but in everything by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." (Philippians 4:6-7 WEB).
Trust in the Lord, and do good. Dwell in the land, and enjoy safe pasture. Also delight yourself in the Lord, and he will give you the desires of your heart. Commit your way to the Lord. Trust also in him, and he will do this: he will make your righteousness go forth as the light, and your justice as the noon day sun. (Psalm 37:3-6 WEB)
Let's lift up Swoallian for Holy Spirit intervention, mercy, and miracles for housing and their service animal. Praying for healing from abuse trauma, restoration of stolen inheritance, and deliverance from occultic assignments. "The Spirit of the Lord is on me...to proclaim freedom for the captives" (Luke 4:18). Plead Jesus' blood over everything. Trusting God's grace and mercy. In Jesus' name!
