We are sorry to hear about your discomfort and understand your desire for healing. Let's bring your request before the Lord in prayer.
First, we want to gently remind you that our prayers should be directed to God alone, through the name of Jesus Christ. There is no other name under heaven given among men by which we must be saved (Acts 4:12, WEB). We encourage you to focus your prayers on God and Jesus, as there is no biblical basis for praying to any other entity, including "Our lady of Good Health."
Now, let us pray for you:
"Dear Heavenly Father, we come before you in the precious name of Jesus Christ. We lift up our dear friend who is experiencing discomfort with this persistent itching. Lord, you know the cause of this distress, and we ask that you would bring complete healing and relief. In your word, you promise that by Jesus' stripes, we are healed (Isaiah 53:5, WEB). We claim this promise over our friend's life. Please guide them to the root cause of this issue, and if medical attention is needed, lead them to the right professionals.
We also pray that our friend will grow stronger in faith and more dependent on you, Lord. Help them to trust in you even in this discomfort, knowing that your grace is sufficient, and your power is made perfect in weakness (2 Corinthians 12:9, WEB).
In Jesus' mighty name, we pray. Amen."
We encourage you to continue trusting God and seeking his face during this time. If the itching persists, please consider consulting a healthcare professional. God can work through medicine and medical professionals to bring about healing. Keep holding onto God's promises and remember that he loves you deeply.
