If your heart were pure then all of nature would be a great book of holy wisdom and sacred doctrine.
Holy wisdom embraces and enables our knowledge, judgment, insight, even as it draws us beyond them. We are given words when we have nothing to say. We are kept silent when we ache to run off at the mouth. We reach out when we would otherwise pull back, cut off, turn away. Our own wisdom is rooted in God's gift of wisdom to us. The soil it grows in is our daily lives, including our relationships with God, ourselves, and others. Only by trusting what little we know, by pushing the edges of our own wisdom, will wisdom grow.
