I spent only one night in the intensive care unit. Then they brought me back to my own room, where I experienced the discomforts that one normally encounters after going through extensive surgery. I wanted to pray, but the physical discomfort was overwhelming. I remember saying to the friends that visited me, "Pray while you're well because if you wait until you're sick you might not be able to do it." They looked at me astonished. I said, "I am in so much discomfort that I can't focus on prayer. My faith is still present. There is nothing wrong with my faith, but in terms of prayer, I'm just too preoccupied with pain. I'm going to remember that I must pray when I am well!"
So this very helpful prayer from the Book of Common Prayer,
O Lord God, almighty and everlasting Father, you have brought us in safety to this new day: Preserve us with your mighty power, that we may not fall into sin, nor be overcome by adversity; and in all we do, direct us to the fulfilling of your purpose; through Jesus Christ our Lord. Amen. (BCP 100)
