God, The Master Physician : Exodus 15:26, Jeremiah 30:17.
Exodus 15:26
26 He said, “If you listen carefully to the voice of the LORD your God and do what is right in his eyes, if you pay attention to his commands and keep all his decrees, I will not bring on you any of the diseases I brought on the Egyptians, for I am the LORD, who heals you.
Jeremiah 30:17
17 For I will restore health to you,
and your wounds I will heal,

Dear Lord,
I have to surrender this to YOU as I cannot face this ordeal.
Please give my son strength as he is my caretaker.
Just guide me, take away my anxiety as I am so afraid.
in this I pray,
Amen
Precious Lord Jesus, you came into the world to heal our infirmities and endure our sufferings. You went about healing all who were sick and bringing comfort to those in pain. By a simple command you rebuked Peter’s mother-in-law’s fever. You spoke directly to the illness, condemned it for its actions and commanded it to leave her body.
In the same way, Lord, you have called all of your disciples to follow your example. You have given us power over all the works of the enemy and sent us forth to make disciples of all nations. In the healing tradition of the church, and through my obedience to your written Word, I hereby take authority over all forms of sickness and disease that have attacked my health.
In the name of Jesus, under the power and authority of the Lord God Almighty, I command all forms of demonic illness to leave my body now and go straight to the feet of Jesus Christ. Your assignment and influences are over. I rebuke all pain in the name of Jesus, and I command it to get out of my body now. I rebuke all spirits of infirmity, nerve disorder, lung disorder, brain disorder, heart disease, AIDS, cancer, hypochondria, fatigue, anorexia, leukemia, arthritis, tumors, abnormal growths, diabetes and all other forms of sickness to leave my body now in the name of Jesus.
Lord Jesus, I thank you for your healing power. I ask you to send forth your ministering, medical and surgical angels, to repair and restore any damage that was caused in my body by the presence of sin, sickness or demonically influenced infirmities. I ask that you send forth your Holy Spirit and fill me with your love, light, peace and joy. Come Holy Spirit and transform me into the child of God that you intended me to be.
in this I pray
Amen
