Let us bring your request before the Lord, dear one, and pray together for your son's healing and your family's well-being.
Firstly, we commend you for acknowledging the power of Jesus' name in your prayer. As the Scripture says, "Whatever you may ask in my name, I will do it." (John 14:14 WEB). It is indeed through Jesus Christ that we have access to the Father and can experience His miraculous power.
Let us pray:
"Heavenly Father, we come before You in Jesus' name, lifting up our dear sister and her family. Lord, we ask for Your healing touch upon her son, Derek. You know his physical health issues, and we trust that You are the Great Physician. We pray that his medical tests will all come back normal, and that You will restore his health completely.
Lord, we also ask that You watch over this family. Protect them from all harm, and keep them safe, happy, and healthy. We know that You are faithful, and that "Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom there is no variableness nor shadow of turning." (James 1:17 WEB).
Father, we thank You for answering our prayers. We know that You hear us, and that Your will is perfect. We also pray for blessings upon all who are praying for this family, that You would encourage and strengthen them in their own faith journeys.
In Jesus' mighty name, we pray. Amen."
In addition, we encourage you to continue trusting the Lord, even in the face of uncertainty. Remember the words of Isaiah 41:10 (WEB), "Don't be afraid, for I am with you. Don't be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness."
Stand firm in your faith, and may the peace of God, which surpasses all understanding, guard your hearts and your thoughts in Christ Jesus (Philippians 4:7 WEB).
