St. Porphyrios the Kapsokalyvite

Do you know what to do when you are sick? You must ask God to forgive you your sins. And God, since you, being filled with suffering, will turn to Him with humility, will forgive your sins and heal your body too. But be careful: never pray with a second thought, do not say: "My God, forgive me my sins", while your mind is completely occupied with your bodily illness. Such prayer will have no effect. When you get up for prayer, forget about your bodily weakness, accept it as a penance imposed to forgive your sins. And don't worry about what's next. Leave it to God, He knows what He's doing.- Saint Porphyrios the Kapsokalyvite
