"The angels praise God obediently. They use their voices and their lyres to praise God's creation. Those of us on earth must also worship God in two ways. First, we should praise, and second, we should do good works.
God is known by our praise, and God's miracles are seen in our acts of kindness because we're filled with God's love and are happy to be doing the Lord's work diligently. All of God's miracles are accomplished through our praise and through our kindnesses."
~Hildegard of Bingen, The Book of the Rewards of Life~
