What prompts this surrender -- this total turning to God in self-donation and makes it possible is the realistic recognition that my very life and being is a gift of love. It is a recognition which becomes experiential in contemplative prayer, in a "knowing" that is beyond knowledge; it is the graced knowledge of love. Only such a gift can make unconditional self-surrender possible, for it is an experience of the unconditional love of a person,a personal God. It is such a recognition that breaks forth joyously in Daniel Berrigan's "All, all is gift. Give it away. Give it away."
Gratefulness has three steps: not missing the opportunity, appreciating the opportunity, and using or enjoying the opportunity. By this method we come fully alive, full of joy, which is what we are all longing for.
