We see the face of God daily, easily recognizable in a spectacular sunset or in a child's smile. And it also exists in less attractive presentations. Can we accept seeing God in the person of our "enemy"? If we can't, we are doomed to propagating lives of hatred and revenge. Only when we see the face of God in everyone and in all things will we be at peace within ourselves and, more importantly, enable peace to exist throughout the world.
In this latter part of life, my prayer of the heart is most often without words. My tongue is stilled. My mind is stilled. The prayer of the heart becomes the heart's own respiration. I breathe in and I breathe out. It is God's breath. God breathing in, God breathing out. It is God's breath breathing me.
