Out of Mormonism by Judy Robertson provides the account of Judy and Jim Robertson's journey into Mormonism. Judy had been someone disappointed with the Christian church that her family attended in her hometown of Fayetteville, Arkansas. She had a dust-up with the co-director of the church's Vacation Bible School and was at a loss as to how to handle the conflict because, she relates, she had not lived with the strength of the scriptures. Even though she had been a Christian all her life, she had never really studied the Bible and therefore did not have the wisdom necessary to handle crises and live the daily life of a Christian.

Jim took Judy and their two children with him to Mesa, Arizona, on what was part family vacation and part work. He had to oversee the potato harvesting for his client, Campbell's Soup. Jim had boasted about some friends he had made during his many trips to Mesa. Joe Jackson was one of the finest people he had ever met. Judy was a little apprehensive. She knew that Joe and his family were Mormons, a religion which she knew nothing about. Once the Robertsons had settled in, she agreed with her husband that Joe and the other Mormons they met were wonderful people.

There was an emptiness within Judy and felt she was not fulfilled spiritually. The Mormon people were welcoming and invited the Robertsons and their children to join them for Sunday services at the nearby chapel. The Robertson's eagerly accepted their invitation and began attending the church. Soon, the Robertsons were under pressure from all directions to join the church. Partly from a feeling of wanting to belong and make friends, both for themselves and their children, they eventually caved to the pressures and joined the church. They returned to Arkansas and joined a Mormon church in the area, although the congregation size was very small. After a year, the family returned to Arizona where they were accepted as full LDS members after a year of probation. The strange ceremony they endured in the temple was unsettling. They were warned not to tell any outsiders about what went on in the temple.

Seven years passed and Judy struggled to live up to the demands of the Mormon church but was overcome with a growing depression and a nagging that she had lost the God she had loved all her life. A business venture took the family back to Mesa, where they moved permanently. A short time after they returned to Mesa, Judy and Jim began reading the Bible and both realized that the Mormon religion was a false religion—a religion that did not follow the laws of the Lord but were guided by those of man.

The Robertsons left the church and received no support or understanding from any Mormons, even those who they thought were good friends. They banded together with other ex-Mormons and dissatisfied Mormons and created a group called Concerned Christians. The group counseled others through their difficult times and decisions to turn to Christ and away from the Mormon church. The group had an international outreach and helped Christians around the world to resist the lure of Mormonism.
