1. Preach by example, even more than in words.
St. Francis of Assisi said to his brothers, "Since it is God's will for us to work, not only for our own salvation, but also for the salvation of others, we will go all over the world to preach-by example, even more than in words - penitence and peace.
2. Reply humbly to those who question you; and for those who shall persecute you, show them your gratitude.
Among those whom you will meet, some will give you a good reception and will listen to you; but the greater part will reject you and revile you. Reply humbly to those who question you; and as for those who shall persecute you, show them your gratitude.
The brothers began to tremble so much that St. Francis had to reassure them.
"Do not feel sad at my ignorance and your own," he said to them.
"God will keep His promise and speak by your mouth. Besides, the time is at hand when wiser men will come and help us. And do not be discouraged any more about your small number." This talk restored their courage.
3. Put your trust in the Lord, who will take care of you.
All dropped to their knees. Francis blessed them and tenderly embraced them, saying, "Dear brother, put your trust in the Lord, who will take care of you." He then dismissed them.
4. They greeted all whom they met with their usual, "God give you peace!" letting it be understood, no doubt, that they themselves possessed this peace and found it good.
People they met were so gruff (curt, short) that a timid brother asked St. Francis not to have to greet people in this way. But the Saint said to him, "Let them be, as these men do not discern yet what comes from God. For the Lord himself revealed this greeting to me. And it is the Lord, too, who has raised up our little brotherhood, which is bound to distinguish itself from others in this-that all its wealth must consist in possessing Him alone."
