C.S. Lewis on prayer

I'm plowing through a book of letters by Lewis and in one letter, I found a thought one on prayer worth posting. He was writing to his friend Arthur Greeves who had asked for prayer. On that subject, Lewis said the following about praying for his friend.

"It may not do you any good, but it does me a lot, for I cannot ask for any change to be made in you without finding that the very same needs to be made in me; which pulls me up and also by putting us all in the same boat checks any tendency to priggishness." (p.53)

This makes me think of what I consider one of the most important ideas from Romans, we are all "in the same boat" with the same problem and all need the same solution.
