In Stratford, Ontario in 1904, William Spence, a medical studenton the verge of becoming a doctor, receives "The Call" while passing a Methodist church one Sunday. His bride-to-be, Hope Morris, accepts his decision to enter the ministry with a whole heart despite the disappointment of her prominent and affluent parents. Will "dives right in", but with no vacancies in Canada, is posted as a circuit minister to a small town in rural Iowa, beginning a life for them of frequent moves around the district, dingy parsonages, and scraping a living from poor boxes and performing weddings. Hope yearns for a decent parsonage and a sense of permanence for their children, but uncomplainingly provides them a good life and a supportive home for Will. For his part, Will understands his own nature and laughs at his own foibles, bending where he can in good conscience. He often enters situations in anger or to instruct but leaves humbled and renewed in spirit. While Will sincerely lives by and teaches by example the tenets of the MethodistDiscipline, he also learns from his congregations to be flexible and change with the times. When their third child, a boy, is born, Hope and Will cannot agree on a name and he remains unbaptized for three months. Hope wants to name the baby William Spence Jr., but Will does not like the idea of his son going without a middle name as he did. He wants the boy to have and be called in "the good old Canadian custom" by the middle name of Frazer. Will seems to give in to Hope but the following Sunday baptizes him William Frazer Spence. Hope serenely accepts the change. Oldest son Hartzell has a hard time coping with the idea that a minister's son should be an example to the other boys. Will explains that "a pastor's family walks a tightrope, balancing with one foot on earth and one foot already in Heaven." After learning that Hartzell has been sneaking into the movies, a pastime seemingly forbidden by the Discipline, Will takes him to the theater to point out why the film is bad for him. They see a western but rather than finding it sinful, Will is impressed by its moral. The following Sunday he preaches a sermon advising his congregation that young people may have something to teach their elders. In the 1920s, the family is assigned to a church inDenver, Colorado, that, despite having many well-heeled members, is old, uncomfortable and decrepit. In a time of economic prosperity for the country, the Spences cope with possibly their most dilapidated parsonage yet. Will has come to appreciate his wife's serenity with life and resolves to provide her a decent parsonage by building a new church. His plans at first are thwarted by power struggles among several snobbish members of the church. He loses one wealthy patron, Mrs. Sandow, to the Baptists when he refuses to stop ministering to her chauffeur, and another, influential banker Preston Thurston, after organizing a children's choir to replace the off-key church choir, run for years by Mrs. Thurston, her family and social circle. Soon after, Hartzell is expelled from school because of a gossip campaign falsely accusing him of making a young girl pregnant and forcing her family to move to San Francisco. A deeply discouraged Will investigates a job offer in California that offers the beautiful church and parsonage he and Hope have always dreamed of but discovers that he cannot surrender in his struggles with the Thurstons. He seeks out the girl's family and learns that there is no truth to any part of the rumor. Returning to Denver, Will confronts Mrs. Thurston and her circle, who started the rumors to punish Will, and suggests that if they don't contribute substantially to the building of the new church, he will call them out in his sermons. A repentant Mrs. Sandow begs to return to the church and Will inveigles from her the stained glass window, new Skinner organ, and carillon that as luxuries are being cut from the plans to finance a recreation center for the church. A year later, their dream church and parsonage finished, Will accepts the challenge of returning to Iowa to aid a small church in trouble, confident that he leaves behind a revitalized church when its members, including all those with whom he locked horns, gather spontaneously on a weekday morning to sing The Church's One Foundation as he plays it on the new carillon.
