The power of appreciation comes through actions. Feeling gratitude creates a wonderful internal experience; expressing it allows us to feel the full bloom of appreciation. Most significant would be our willingness on a moment-to-moment basis to find some aspect of every person and event to appreciate and then find a tangible way to express our gratitude.
We need silence to be able to touch souls. The more we receive in silent prayer, the more we can give in our active life. God is a friend of silence. The essential thing is not what we say, but what God will say through us.
