Lord, I lift this person to you and pray that you would touch his life with your miraculous healing power. I pray Father that you would undertake for this man in every situation as he puts you first in his life. God bless 

Father in the name of Jesus that this person that I do not know you know. You are a merciful and graceful God. Father I know that I am in a similar position he is in and you have never forsaken me. I ask that the manifestation of his healing manifests in him as it is in me. Father I thank you that you are a covenant keeping God, and that if we serve you with all our heart you lord said that you would bless our bread and our water and remove sicknessa and disease from the midst of us. So father even though I don't know this person show him a sign of encouragement Father. Bless him also with the gift of marriage as you have recently done for me. Father I thank you that you promised that you would give us the desires of our hearts and that you perfect all things concerning us. In Jesus' name, let him be healed. Hallelujah!
(on a personal note I just wanted you to know that I am also believing for my healing from a spinal cord injury from 3 years ago. I have also recently become engaged which was something I really had been praying for. Let me tell you brother God is FAITHFUL)
