Obeying the Gospel explores the history of the Church of Jesus Christ of Latter-day Saints during the 19th Century, and its earliest foreign missions, that sustained its existence against religious persecution in America. It highlights the preparation of the early Apostles who traveled across borders and oceans to bring new blood into the membership of the Church through its most trying and difficult times. Physical sacrifice and endurance against political and religious persecution were the challenges overcome by obeying the Gospel.
