"The Lord in the Doctrine and Covenants tells us to be 'anxiously engaged in good causes'. This suggests we can't respond to all causes. We must be selective in the things we seek to do in terms of community and civic chores. But it also suggests we ought to devote a measure of our time and talent to do these things, for they do count on the scales of action as God sees it.
"The world is full of fads. The world is full of the marches of lemmings to the sea. The world is full of causes that lead into conceptual cul-de-sacs. Our task, therefore, is to be wise in the selection of good causes, using the scriptures and the modern prophets as our guide.
"Anne Morrow Lindbergh, in her book Gift from the Sea, says: 'My life cannot implement in action all the demands of all the people to whom my heart responds.' You will care for more things than you will be able to do things about. Wise selection of causes is one of the highest forms of the uses of free agency that there is, and, really, one of the ways God tests our basic wisdom and our capacity to love."
