Isabella often received invitations to speak to Christian organizations and she accepted as many as she could. Sometimes she would speak to the group on a topic that was dear to her heart, but often she would read one of her not yet published short stories.
One day she received an invitation to go to a small town and read one of her stories to the “Y.P.S.C.E.”
“It was the first time I had seen those five letters of the alphabet so grouped,” she said, “and I could not decide what they meant.”
She puzzled over those letters for some time and finally decided that the first three initials stood for “Young People’s Society.” But what about the C and E? Why hadn’t the writer explained what the letters meant? How was she supposed to select the right story for her audience when she had no idea of the purpose of the organization?
At last she went to her husband for help and found him reading a newspaper.
“I was just coming to consult you,” Reverend Alden said. He pointed to an article in the newspaper. “I found a splendid name for our young people! This name suggests the very thought we have been struggling for. ‘Young People’s Society of Christian Endeavor.’”
Suddenly Isabella realized the meaning of the initials on that invitation.

The very next day she set out to learn everything she possibly could about the Young People’s Society of Christian Endeavor. She wrote to the Society’s founder, Dr. Francis Clark, or “Father Endeavor Clark,” as he was affectionately called by the young people in the organization. He immediately wrote back with information about the Society, and he invited Isabella attended a Christian Endeavor Convention in Cleveland, Ohio. There she met Dr. Clark in person.
Her first thought as he cordially shook her hand was, “Why, he is just a young man!”

But she soon realized, after watching Dr. Clark interact with the young people at the convention, that he was an earnest and deeply spiritual leader who had a special gift for inspiring young people in Christian work.

Isabella used her own experiences with the Y.P.S.C.E as the inspiration for her book, Chrissy’s Endeavor. She even incorporated into the story her first encounter with those baffling initials, “Y.P.S.C.E.”
After the book was published, Isabella received an astonishing number of letters praising her book. One such letter read:
“We want to say that we think here that the book ‘Chrissy’s Endeavor’ is doing a work in the world which will be to its author one of the surprises of heaven.”
Isabella remained actively involved in the Y.P.S.C.E, as did her husband and other members of her family. Over the course of many years, she saw the results of the Society’s good works, and she was thankful for having had the chance to know Dr. Clark in person.
In 1897 The San Francisco Call published a full-page article about the Society of Christian Endeavor, with details about how it came to be organized, and it’s growth world wide to over two million members. Click on this link to read the article.
