We must lay one brick at a time, take one step at a time; we can be responsible only for the one action of the present moment. But we can beg for an increase of love in our hearts that will vitalize and transform all our individual actions, and know that God will take them and multiply them, as Jesus multiplied the loaves and fishes.
When a person is angry with another person, that person is removed from their heart. That's why the physical reaction is to shout. The greater the distance, the louder the shouting. But when individuals are in love, they speak softly, and when they are further in love, no words are needed.
