Lord God, thank you that you love [name of person who needs healing]. I know that you hate what their illness is doing to them/me. I ask that you would heal this disease, that you would have compassion and bring healing and comfort from all sickness.
Your word says that when we call out to you the Eternal one you will give the order, heal and rescue us from certain death. In the Bible, I have read of miraculous healing and I believe that you still heal the same way today. I believe that there is no illness you cannot heal after all the bible tells of you raising people from the dead so I ask for your healing in this situation.
I also know from my experience of life on earth that not everyone is healed. If that happens here than keep my heart soft towards you, help me to understand your plan and help me to be excited about heaven.
God, I thank you that [name of person who needs healing] belongs to you and that you are in control of everything that happens from our first breath to our last sigh.
