We are truly sorry to hear about your grandchild's health condition. We will stand with you in prayer and faith, trusting in the healing power of our Lord Jesus Christ.
Firstly, we would like to remind you that God is always with us in times of trouble. As it says in Psalm 46:1 "God is our refuge and strength, a very present help in trouble." (WEB). Also we need to remember to pray in the name of Jesus. It is only by the name of Jesus that we have access to God. And there is no other name by which we can be saved, 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!"
Let us pray together:
"Heavenly Father, we come before you in the name of Jesus, lifting up this precious grandchild. Lord, you know the pain and discomfort he is experiencing, and we ask for your healing touch upon his foot. We pray that the doctors will have wisdom and discernment to accurately diagnose and treat his condition. If it is MRSA or any other infection, we command it to leave in the powerful name of Jesus.
Father, we know that you are the Great Physician, and there is no sickness or disease that can stand against your power. We claim your promise in Matthew 21:22, 'All things, whatever you ask in prayer, believing, you will receive.' We believe in faith that this child will be healed and restored to full health.
Lord, we also pray for the family during this time. Give them strength, patience, and unwavering faith in your goodness. Help them to trust in your plan and to rest in your love. In Jesus' name, we pray. Amen."
Continue to trust in the Lord and keep your eyes fixed on Him during this challenging time. Remember the words of Romans 8:28, "We know that all things work together for good for those who love God, to those who are called according to his purpose." (WEB). Keep praying and believing, and may God's peace and comfort be with you and your family.
