A person must learn to be alone in solitude, to listen in one's heart to the wordless speech of the Spirit, and to discover the truth bout oneself and God. Then their word to others will be a word of power, because it is a word of silence.
When we are able to trust our calling and accept the journey we've been handed, we trust in a wisdom beyond our comprehension, remembering that no matter what happens, we are part of sacred creation.
