I am in mid-life crisis. I know this because I am intently aware of my dissatisfaction with what I have accomplished and who I have become. Imagine my delight to hear the words of a wise teacher who tells me never to be satisfied!
St. Columbanus tells us "...that is lovely to excess which is ever eaten and drunk, and ever hungered and thirsted after, ever tasted and ever desired, wherefore the prophet-king [David] says, 'Taste and see how lovely, how pleasant is the Lord.'"
God does not desire to satisfy us. His desire is to feed us over and over again in loving relationship. The more we taste of God's goodness the more we desire, and this is God's joy and ours.
