Difficulties should not depress or divert us. The cause that has gripped us is so great that the small weaknesses of individuals cannot destroy it. Therefore I ask you only one thing: do not be so worried about yourself. Free yourself from all your plans and aims. They occupy you far too much. Surrender yourself to the sun, the rain, and the wind, as do the flowers and the birds. Surrender yourself to God. Wish for nothing but one thing: that his will be done, that his kingdom come, and that his nature be revealed. Then all will be well.
