You know my friend/family member so much better than I do. You know his/her sickness and the burden he carries. You also know his heart. Lord, I ask you to be with my friend now as you work in his life.
Lord, let your will be done in my friend's life. Lord, I pray for my friend just as your Word tells me to pray, for healing. I believe you hear this earnest prayer from my heart and that it is powerful because of your promise. I have faith in you, Lord, to heal my friend, but I also trust in the plan you have for his life.
Lord, I don't always understand your ways.
I don't know why my friend has to suffer, but I trust you. I ask that you look with mercy and grace toward my friend. Nourish his spirit and soul in his time of discomfort and comfort him with your presence.
Let my friend know you are there with him through this difficulty. Give him strength. And may you, through this difficulty, be glorified in his life and also in mine.
