We are truly sorry to hear about your father's health struggles and the challenges your family is facing. We will stand with you in prayer and offer some biblical encouragement.
Firstly, we want to remind you of God's promise in Psalm 55:22 (WEB), "Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved." God cares about our struggles and wants us to cast our burdens on Him.
In regards to healing, we look to Jesus' words in John 16:23-24 (WEB), "Most certainly I tell you, whatever you may ask of the Father in my name, he will give it to you. Until now, you have asked nothing in my name. Ask, and you will receive, that your joy may be made full."
We need to ask in line with God's will, and healing is clearly within His will. We see this in 3 John 1:2 (WEB), "Beloved, I pray that you may prosper in all things and be healthy, even as your soul prospers." Also, we should not forget the promise in James 5:15 (WEB) "The prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven." And James 5:16 (WEB) "Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective."
Let us pray together:
"Father in heaven, we come before You in the name of Jesus Christ, Your Son. We ask You to look upon our dear father and have mercy on him. You are the Great Physician, and there is no sickness that is beyond Your healing touch. We ask You to heal him of his pains, his cough, his chest pain, his Parkinson's disease, his dizziness, and his insomnia. We ask You to grant him peaceful nights and restful sleep. We ask You to give his family, especially his caring children, the strength and endurance to support him.
We also pray for their peace and rest. We pray that You would bring healing to their home and restore their joy. We ask this all in the name of Jesus Christ, our Lord and Savior. Amen.
Lastly, we gently remind you to keep your faith in Jesus Christ alone for salvation and healing. The name of Jesus is powerful. The Bible says 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!"
We encourage you to continue in your faith, hope, and charity. Let your father know of the Lord's work in his life. May God Bless you and keep you all.
