Let's bring your requests before the Lord together, seeking His will and guidance.
Firstly, we want to encourage you to cast all your anxieties on Him, because He cares for you (1 Peter 5:7 WEB). It's important to remember that it is not by our own strength that we are healed or helped, but by the power of Jesus Christ. It is only by the name of Jesus that we have access to God. As it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB).
Let's pray for your healing:
Dear Heavenly Father, we come before You in the name of Jesus Christ, seeking Your healing touch for our ###. Lord, You know her pain and discomfort. You know her persistent cough and the weakness in her neck and shoulder. We ask, Lord, that You would heal her, that You would strengthen her body, and that You would give her renewed health and energy to serve You and others. Help her to trust in Your goodness and grace in the midst of her trials and to rest in Your strength. Help her to be completely healed and unburdened. In Jesus' name, we pray. Amen.
Regarding your husband and his family, it's important to remember that our battle is not against flesh and blood, but against the rulers, against the authorities, against the world rulers of this darkness, and against the spiritual forces of wickedness in the heavenly places (Ephesians 6:12 WEB). We should pray for them, that they would be drawn to God and experience His comfort and peace.
Let's pray for your husband and his family:
Dear Lord, we lift up our ###'s husband and his family to You. Lord, You know the pain and struggle they are going through. We ask, Lord, that You would be with our ### giving her comfort and guidance at this time of need. Holy Spirit, we ask that You would fill our ### with the words to say to her husband that would bring healing, encouragement, and comfort. We ask for wisdom as she seeks to do her best to support her husband and his family. Also, Lord, please be with our ###’s husband’s mother. We know that she needs your presence and comfort. We ask for healing, but we are also asking that she be given salvation in the name of Jesus if she does not already know Jesus. We ask You to be with the entire family and to bring them to Christ.
Finally, ###, remember that you cannot save or change people; only God can. Our responsibility as Christians is to love them, pray for them, and share Christ's love and truth with them. You are right to want to be there for your husband and his family, but be sure to do this in His strength and not your own. You can only truly help when your own health and strength is restored.
In all things, keep your eyes on Jesus, the author and finisher of our faith. In Him, you will find the strength and wisdom to face whatever comes your way. It is only by Jesus' name and in Jesus we must pray. This is the only way we can be saved. As it is written, "In him was life, and the life was the light of men" (John 1:4 WEB).
As a reminder, we do not pray to Mary, an angel, or non-living saints, but to God alone in Jesus Christ.
Furthermore, we encourage you to be blessed by God and continue in the good works to be done for God's glory. This is only possible through Jesus Christ as it is written, "But as many as received him, to them he gave the right to become God's children, to those who believe in his name" (John 1:12 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!
