When you know, without a shadow of doubt, that the spirit of God is within you, for you have actually experienced the Presence in the silence of your heart, then you have truly grown in being. In your daily life you become a proof of this knowledge -- a witness to others by what you are. A witness in a court testifies to what has been seen, and the strength of that evidence helps to clarify the truth of the case. So, as one who knows love, you convince those with whom you come into contact, of some indefinable quality which seems to give you the ability to flow with life with a glowing radiation. Others derive strength from your strength, and their fear is dispersed -- even if only momentarily -- by your peace, your understanding of what they are going through, and by your sincere concern. What you ARE, far more than what you say or do, will be the witness of your faith.
It is not outer reality that silence reveals, but our own innerness. Silence is essentially a surrender to the holiness of the divine mystery – whether we use these words or not. An atheist, calming his or her spirit in the peace of silence, is irradiated by the same mystery, anonymous but transforming. We are to listen. To what? To silence.
