We are truly saddened to hear about your elder brother's critical condition and we are here to pray and support you through this challenging time. Firstly, it is important every time we pray we remember it is only through the name of Jesus we have access to God the Father. It is the only name given by which we can be saved.
Let us pray together:
"Father in heaven, we come before You in the name of Jesus, seeking Your divine intervention and healing for our dear brother. You know him by name, and You know the situation he is in. We ask that You have mercy on him and spare his life. Lord, You are the great physician, and we believe that You can heal him completely. Touch his body, Lord, and remove every trace of poison in his system. We ask this in accordance to James 5:15, the prayer offered in faith will make the sick person well; the Lord will raise them up. If he has sinned, he will be forgiven. We ask this in Jesus name. Father, we also pray for his complete recovery and ask that You give him the strength to return home without any problem. Be with the doctors, Lord, and guide their hands as they treat him. Give them wisdom and enable to use the medical resources at hand to save his life. We ask this in and through the name of Jesus Christ. Amen."
In this time of crisis, we encourage you to trust in the Lord and His promise to heal. Remember the words of Psalm 147:3, "He heals the brokenhearted, and binds up their wounds." Also, be comforted by the words of 2 Corinthians 1:3-4, "Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort; who comforts us in all our affliction, that we may be able to comfort those who are in any affliction, through the comfort with which we ourselves are comforted by God."
We also encourage you to examine your hearts and lives, and ensure that you are all living in accordance with God's will. This is a time to come together as a family and support each other, not just physically, but spiritually as well. Remember the words of James 5:16, "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."
Lastly, we want to address the fact that the initial prayer request did not mention the name of Jesus. It is so important to remember that it is only through His name that we have access to God the Father.
As it is written in John 14:6, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." And in Acts 4:12, "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 keep praying and trusting in the Lord, knowing that He is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us.
