Her most famous book, The Hiding Place, is a biography that recounts the story of her family's efforts and how she found and shared hope in God while she was imprisoned at the concentration camp.

She quickly discovered that she loved the "business side" of the watch shop, and she organized the financial proceedings by developing a system of billings and ledgers.

[7] Over the next decade, in addition to working in her father's shop, she established a youth club for teenage girls, which provided religious instruction and classes in the performing arts, sewing, and handicrafts.

[3] She and her family were Calvinist Christians in the Dutch Reformed Church, and their faith inspired them to serve their society, which they did by offering shelter, food and money to those who were in need.

[3] Some important tenets of their faith included the fact that the Jews were precious to God[6] and that all people are created equal[8] – powerful motivation for the selfless rescue work she would later become involved in.

[9][page needed] In May 1942, a well-dressed woman came to the Ten Booms' with a suitcase in hand and told them that she was a Jew, her husband had been arrested several months earlier, her son had gone into hiding and Occupation authorities had recently visited her so she was afraid to go back.

"[11] Corrie and her sister Betsie opened their home to Jewish refugees and members of the resistance movement, and as a result, they were sought after by the Gestapo and its Dutch counterpart.

Through her charitable work, Ten Boom knew many people in Haarlem and remembered a family with a disabled daughter, whose father was a civil servant who was now in charge of the local ration-card office.

[10] She went to his house one evening, and when he asked how many ration cards she needed, "I opened my mouth to say, 'Five,'" Ten Boom wrote in The Hiding Place.

Ten Boom's involvement in the Dutch resistance grew beyond gathering stolen ration cards and harboring Jews in her home.

Though the house was under constant surveillance after Ten Boom's arrest, police officers who were also members of the resistance group coordinated the refugees' escape.

The refuge housed concentration-camp survivors and until 1950 exclusively sheltered jobless Dutch who had collaborated with the Germans during the Occupation, after which it accepted anyone in need of care.

Each chapter tells a short, different story about her world travels and sharing the gospel message in Africa, Europe, the Americas, Asia, and even in difficult-to-reach and dangerous countries such as Russia (then-USSR), Cuba, and China.

It features photographs of Ten Boom and her important messages of forgiveness, hope, love, and salvation through the saving grace of Jesus Christ.

Ten Boom told the story of her family members and their World War II work in her bestselling book, The Hiding Place (1971), which was made into a 1975 World Wide Pictures film, The Hiding Place, starring Jeannette Clift as Corrie and Julie Harris as Betsie.
