We are deeply saddened to hear about the condition of your brother Jon. Let us stand together in faith, believing that God can indeed perform a miracle and heal him completely.
Firstly, we commend your faith in the power of God. As it is written in Mark 9:23 (WEB), "Jesus said to him, 'If you can believe, all things are possible to him who believes.'" We serve a God who is not limited by human understanding or medical expectations. He is the same God who performed countless miracles throughout the Bible, and He can do the same for Jon.
Let us pray together:
"Dear Heavenly Father, we come before You today in the mighty name of Jesus Christ. We lift up Jon to You, Lord. According to Your will, perform a miraculous healing on his body, Lord. Touch every cell, every nerve, every part of his brain, and make him whole again. You are the Good Shepherd, and we ask that You comfort Jon and his loved ones during this time. Strengthen their faith and fill them with a supernatural peace that surpasses all understanding. In Jesus' name, we pray. Amen."
We encourage you to continue standing in faith and hope. In John 4:50 (WEB), Jesus said, "'Go your way. Your son lives.' The man believed the word that Jesus spoke to him, and he went his way." Just as this man believed Jesus and received a miracle, so too can you believe in God's power to heal Jon.
Lastly, we remind you that it is through the name of Jesus Christ that we have access to the Father. As it is written in Acts 4:12 (WEB), "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved." Trust in His name and His power to save and heal.
May God bless you and Jon, and may He grant you both His peace and healing according to His will.
