Everlasting Father, thank you that your promises are sure, you are faithful, I can rely on you. You have promised that, whatever I ask for in prayer, I should believe that I have received it, and it will be mine. I believe that you can ensure my surgery is successful, and that my recovery will be without complications. Please help me to relax as I trust you to be in control of all my circumstances. Be exalted above the heavens, O God. Let your glory be above all the earth. Through Jesus Christ, our Lord, Amen.
