Ruth only sighed.

"I have so many calls to make with father," she said, wearily. "It is the worst work I do. They are upon fashionable, frivolous people, who cannot talk about anything. It is worse martyrdom now than it used to be. I think I am peculiarly unfitted for such work, Dr. Dennis."

"But I want you to try a different style of calls. Go alone; not with your father, or with anyone who will trammel your tongue; and go among a class of people who do not expect you, and will be surprised and pleased, and helped, perhaps. Come, let me give you a list of persons whom I would like to have you call on at your earliest opportunity. This is work that I am really longing to see done."

A prisoner about to receive sentence could hardly have looked more gloomy than did Ruth. She was still for a few minutes, then she said:

"Dr. Dennis, do you really think it is a person's duty to do that sort of work for which he or she feels least qualified, and which is the most distasteful?"

"No," said Dr. Dennis, promptly. "My dear Miss Erskine, will you be so kind as to tell me the work for which you feel qualified, and for which you have no distaste?"

Again Ruth hesitated, looked confused, and then laughed. She began to see that she was making a very difficult task for her pastor.

"I don't feel qualified for anything," she said, at last. "And I feel afraid to undertake anything. But at the same time, I think I ought to be at work."

"Now we begin to see the way clearer," he said, smiling, and with encouragement in his voice. "It may seem a strange thing to you, but a sense of unfitness is sometimes one of the very best qualifications for such work. If it is strong enough to drive us to the blessed Friend who has promised to make perfect our weakness in this as in all other efforts, and if we go out armed in His strength we are sure to conquer. Try it. Take this for your motto: 'As ye have opportunity.' And, by the way, do you know the rest of that verse? 'Especially to them who are of the household of faith.' It is members of the household that I want you to call on, remember."

Ruth laughed again, and shook her head. But she took her list and went away. She had no more that she wanted to say just then; but she felt that she had food for thought.
