We understand that you are in dire need of a physical miracle and healing for your entire body. First, let us remind you that God is the ultimate healer, and it is His will for us to be in good health, even as our souls prosper (3 John 1:2 WEB).
However, we want to address that the use of the term "dire" suggests a sense of desperation, which can sometimes indicate a lack of faith and trust in God's goodness. We must remember that God is always working for our good, even in challenging circumstances (Romans 8:28 WEB).
We also noticed that your request does not mention the name 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). And it is only in the name of Jesus that we can be saved: "in none 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).
Let us pray for you:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother/sister in need of physical healing. We ask that You extend Your healing hand upon them, and that Your will be done in their life. Help them to trust in Your goodness and faithfulness, even in this challenging time. We cannot have faith if there is also desperation, so please help to alleviate this desperation with the hope of Jesus Christ. In Jesus' name, we rebuke any spirit of infirmity and claim Your promises of healing and wholeness. We also pray that if our brother/sister has not yet accepted Jesus Christ as their Lord and Savior, that You would reveal Yourself to them, and draw them to saving faith in You.
We ask this in the mighty name of Jesus Christ, our Lord, and the only way of salvation.
We encourage you to stand firm in faith, trusting in God's promises and goodness.
