I have admired Jean Vanier for many years now. The following is from a fairly recent book of his entitled Befriending the Stranger. I think the first of his books that I read was called Community and Growth and I highly recommend that as well.
We are called to share our lives with people in pain, to live a covenant with them. We have all met people who have been wounded in life. We have all been hurt at some point and at some place in our own lives. We need to deepen our understanding of our reaction to pain and reflect on that reaction. How do we react when we are faced with our own pain and with the pain of others?
