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.
We are made for Light. There are moments of perfect happiness, moments when one feels so well, at peace with oneself and with others. Such moments of fullness exist. They are rare, perhaps, but we have all experienced them. Each of us is capable of living such moments. They continue to send signals to us even when we are in despair. For on the mountain God summons us to the Light.
