I'm amused whenever I hear Isabella cooing and babbling to herself in the backseat; I can't see her but I know what state of mind she's in from the sound of her voice, or her cry, or even the kind of breathing in her sleep--measured, easy, peaceful. It helps me feel everything is alright in the world, regardless of my stress level.
Thinking this through, I placed myself in that spiritually: I believe God understands and listens to the stirrings of my soul, when all is sound and babble. I have days when that's ALL I sound like, and knowing someone's listening is the source of comfort. I know some find this support in the ear of compassion, and we can all be a source for others by our silent listening, wise words, or compelling action. We can reflect our Creator's mercy in this world by our presence to others.
Consider that next time you're traveling along your way, and listen to what comes back to your soul.
