As you said there is a real power in hearing from those living in the condition of their physical vulnerability. If only we could all have a little of that sense of vulnerability and weakness in our daily attitudes in a "go get em" society. The thought that came to me is that this acceptance Karen speaks of becomes a kind of strength we don't expect, as it knits us together into wholeness. She also spoke of hopefulness, which has a very powerful meaning when used as hope beyond desire. One of my favourite psalms is "You know my inmost being: you knew me before I was knit together in my inmost being." (Psalm 139:13). In listening to the question about demanding something ("demandez") of God it causes me to contemplate that God (creator, revealer, knower) is a knower of our hope and accepting of it. He/She radiates back love as an answer, saying like Paul (Col. 2:2) "I want hearts to be encouraged and united (also "knit together"/ "woven") in love." (I am inspired to do some word study/exegetical work on the words "knit", "woven" and "united" and their use and correlations in scripture ... by this discussion). People are making an authentic attempt here to get beyond Babel's blockades of meaning and reach one another's hearts, which is a very hopeful thing in of itself.
When a Christian friend of mine, who has a chronic illness, speaks about her illness on facebook it has a similar quality of acceptance when she openly reaches out to her friends for acceptance of the pain and anxiety she's feeling and through the sharing of the wholeness (holy) of spirit of others, she feels a sense of acceptance from the comments of love and encouragement she receives back. She has told me that for her the cross is the path that helps her understand her life, meaning that she feels God had a complete identification and acceptance of her pain as well, for he has experienced it and wishes for us to heal in the most profound of ways.
