We understand your deep concern and love for your son, and we join you in praying for his healing and protection. It's wonderful that you've invoked the powerful name of Jesus, for it is in His name that we have access to God's throne of grace. As it is written in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
Let us pray together:
"Dear Heavenly Father, we come before you in the name of Jesus Christ, seeking your divine healing and protection for this dear son. Lord, you know his needs and we trust that you are faithful and just to answer our prayers. Please comfort him, Lord, and help him to sleep peacefully. We know that in your presence there is fullness of joy and at your right hand are pleasures forevermore (Psalm 16:11 WEB). We ask that you envelop him in your loving arms and grant him the peace that transcends all understanding (Philippians 4:7 WEB). In Jesus' name, we pray. Amen."
In addition to prayer, we encourage you to trust in God's promise in Jeremiah 29:11 WEB, "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future." God has a good plan for your son, and He is faithful to see it through.
Lastly, we remind you of the importance of teaching your son about the saving grace of Jesus Christ, if you haven't already. It is only through believing in Him that we can be saved and have eternal life (Acts 4:12 WEB, John 3:16 WEB). This will be the greatest gift you can give him.
Keep trusting, keep praying, and keep believing. God is with you and your son.
