This does not mean giving up our dreams for dreariness and duty. It does mean being willing to recognize that the divine view and understanding is much bigger than our own. We must be willing to admit that our opinions are based on limited understanding, that our actions are often based on faulty and unconscious assumptions, that what we think we want may be different from what we really need.
"Not my will but thine be done" means to open to a divine reality bigger than our human views; it means being willing to examine our assumptions; it means that having a life in which we feel humanly organized and in control is not the same as living a life in alignment with Love; it means, most of all, leaning (tentatively or wholeheartedly) into Love, who attends to our truest, deepest needs -- the ones we might not even recognize.
