In all our activities we may be seeking God: in our work, on our social occasions, as we walk along the road, even when we are so busy that we have not time to think of anything except what we are doing... God can deal with us under a thousand forms for our spiritual hallowing. Behind all the strange puzzles of life there is the secret working of God, creating life, creating character, accepting service -- all sorts of spiritual shaping going on.
In being true to the small voice within, you are being of service to others and to the world in the most profound way possible. You cannot know where that voice will take you, but in being willing "to save the only life you could save," you are affirming one of the deepest and most sobering truths of all: no one else can ever walk your journey for you. You alone can respond to your call.
