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.
Where is the wisdom we have lost in knowledge? Knowledge gives us information. Wisdom gives us light on the way. Knowledge is skill. Wisdom is a quality. Knowledge can be learned. Wisdom can only be distilled from those places in life where knowledge is not enough to really explain what was happening to us, or information failed to resolve what was happening to the other.
