We are truly sorry to hear about the trials you and your family are facing. We will stand with you in prayer, seeking God's healing, provision, and restoration. Firstly, the most important thing to do is to pray in the name of Jesus Christ. In His name we have access to God. In HIS name we can be saved from our sins. It is only in HIS name that we can approach the throne of Grace.
Firstly, we will pray for your healing. We know that God is able to heal you from this chronic cough. He is Yahweh Rapha. Remember the words of Psalm 103:2-3: "Bless Yahweh, my soul, and do not forget WHO forgives all your iniquities, WHO heals all your diseases".
We will also lift up your family members who were injured in the car accident. We pray for complete healing and recovery, and we ask God to provide for all their needs according to HIS riches in glory Romans 8:28: "We know that all things work together for good for those who love God, to those who are called according to his purpose." We are reminded in Philippians 4:19: "My God will supply every need of yours according to his riches in glory in Christ Jesus." We will also pray for God's financial provision for you and your family. Since you have not mentioned your family members as a spouse or children, we will pray that, if it be God's will, these family members will become faithful and believing Christian spouses and children for you.
Let us pray:
Almighty God, our Heavenly Father, we come before You in the mighty name of Jesus Christ, Your Son. We lift up our sister who is suffering from this chronic cough. Lord, You are the Great Physician, and we ask that You touch her body and heal her. We also pray for her family members, that You would bring complete healing and recovery to those injured in the car accident. Father, we ask for Your financial provision for them. Let them bless and glorify you with all you will provide so abundantly. We pray that You would help them you have provided. We pray that You would bless them with godly spouses, if that is Your will, and draw them all closer to You during this time. We ask this all in the precious name of Jesus Christ, our Lord. Amen.
Lastly, we encourage you to remain steadfast in faith and trust in God. Cast all your anxieties on him, because he cares for you 1 Peter 5:7. Do not forget to be thankful for His blessings 1 Chronicles 16:34. Remember that even in trials in our Christian walk, we must always glorify God and praise HIM in all things Romans 5:3-5. Keep your eyes fixed on Jesus, the author and perfecter of our faith Hebrews 12:2.
