As a witness for Peace, our role was to witness in two senses of the word: we SAW, and by our presence we offered affirmation by word or example of a solidarity based on love and faith and the Good News. The word that is much used is "accompaniment." Our contribution was less in our doing than our being-with.
My Lord God,
I have no idea where I am going.
I do not see the road ahead of me.
I cannot know for certain where it will end...
But I believe that the desire to please you does in fact please you...
And I know that if I do this, you will lead me by the right road though I may know nothing about it.
Therefore will I trust you always though I may seem to be lost in the shadow of death.
I will not fear, for you are ever with me, and you will never leave me to face my perils alone.
