To say "I believe in God" means that I commit myself to make God a presence in the center of my heart, in the humdrum of my days, in the dregs of my struggles. Discovering the way God works in each of those is the spiritual journey of a lifetime. It is the ultimate spiritual task. It is the quest for the Holy Grail that is buried in recesses of my own life.
