In His Steps takes place in the railroad town of Raymond, probably located in the eastern U.S.A. (Chicago, IL and the coast of Maine are mentioned as being accessible by train), and Chicago Illinois. The main character is the Rev. Henry Maxwell, pastor of the First Church of Raymond, who challenges his congregation to not do anything for a whole year without first asking: “What Would Jesus Do?” Other characters include Ed Norman, senior editor of the Raymond Daily Newspaper, Rachel Winslow, a talented singer, and Virginia Page, an heiress, to name a few.
The novel begins on a Friday morning when a man out of work (later identified as Jack Manning) appears at the front door of Henry Maxwell while the latter is preparing for that Sunday’s upcoming sermon. Maxwell listens to the man’s helpless plea briefly before brushing him away and closing the door. The same man appears in church at the end of the Sunday sermon, walks up to “the open space in front of the pulpit,” and faces the people. No one stops him. He quietly but frankly confronts the congregation—“I’m not complaining; just stating facts.”—about their compassion, or apathetic lack thereof, for the jobless like him in Raymond. Upon finishing his address to the congregation, he collapses, and dies a few days later.
That next Sunday, Henry Maxwell, deeply moved by the events of the past week, presents a challenge to his congregation: “Do not do anything without first asking, ‘What would Jesus do?’” This challenge is the theme of the novel and is the driving force of the plot. From this point on, the rest of the novel consists of certain episodes that focus on individual characters as their lives are transformed by the challenge.
Norman decides not to print a prize fight, and to discontinue the Sunday edition, leaving a drop in subscriptions. Alexander Powers starts a small meeting for the railroad men, but also discovers the railroad's fraud against the ICC. He resigns his post, and goes to work as a telegraph clerk. Rollin Page proposes to Rachel Winslow, who rejects him, because he has no direction. Later Rachel and Virginia help Mr. and Mrs. Gray with meetings in the Rectangle (an area surrounded by saloons), and Rollin experiences conversion. Later, Virginia takes Laureen, a drunken lady who was earlier converted, to her house, to the dismay of her grandmother who leaves for high society. Jasper Chase, against the "What Would Jesus Do" vow, decides to print his novel anyways. Virginia later uses her inheritance to buy the Rectangle property and also to help Norman's newspaper. Rollin, having a purpose for his life helping people, declares love for Rachel.
Chapters 16–24 shift the action to Chicago, with Dr. Calvin Bruce from Chicago visiting Raymond, and writing what he saw. He then decides to try similarly. Dr. Bruce does a similar pledge. His bishop, Bishop Edward Hampton visits him also. Rachel's cousins, Felicia and Rose are orphaned when their father commits suicide and their mother dies of shock. They go to live in Raymond for a little bit. Dr. Bruce and the Bishop start a work in the Settlement (similar to the Rectangle), with help from Felicia. The Bishop is held up, but the robber realizes the Bishop was the same person who helped him, and he reforms. Some of the characters from the earlier chapters, such as Henry Maxwell, Rachel Winslow, appear to see the work in the Settlement. The last chapter has a vision Henry Maxwell sees, telling some of the future of many of the characters in the book.Jesus appears quietly at first, to one person and then to an expanding group of people in the small town of Raymond. He gradually draws more and more attention, including crowds. Jesus goes from Raymond to New York City and then Washington D.C., at points making a public splash, including media attention. The non-stereotypical character of Jesus seems fully capable of supernatural power (not showing up in pictures, for example), but chooses a nondescript mode of presenting himself. He does not appear to do dramatic public acts such as healing, but instead speaks words of comfort or lends practical help. He has views but relays them with understatement. He wears ordinary business clothes, at times blends into a crowd, and is not memorable in appearance. He is humble, practical and personable. His impact upon lives is not through obvious miracles, but old-fashioned kindness, care, and encouragement.
