"The World's Great Sermons, Volume 05: Guthrie to Mozley" by Grenville Kleiser is a collection of profound theological discourses likely compiled in the early 20th century. This volume includes sermons from notable preachers such as Thomas Guthrie and Frederick Denison Maurice, each reflecting on critical elements of Christian faith and morality. The book aims to inspire readers through the eloquent expressions of religious thought and the exploration of spiritual themes central to Christian doctrine. The opening portion of the volume introduces Thomas Guthrie's sermon titled "The New Heart," which emphasizes the necessity of spiritual renewal and transformation through divine grace. He speaks to the condition of the human heart, contrasting the hardened, stony heart with a renewed, living heart that is responsive to God's will. Guthrie articulates the process of conversion, explaining how a true believer undergoes a significant change in affections and desires, ultimately aligning themselves with Christ. He illustrates these concepts with vivid metaphors and personal anecdotes, establishing a foundational principle of Christian belief: that one's heart must be transformed to truly embrace faith and the love of God.
