The Most Powerful Prayer on Earth is a 2004 book on Christian spirituality by Peter Horrobin. The aforementioned prayer, Horrobin says, is Jesus’s in Luke 23:34: “Father, forgive them, for they do not know what they are doing.”
Here, based on Jesus’ model and teaching, Horrobin discusses the need to forgive any and all who have hurt us, whether spiritually, physically, emotionally, or sexually; the freedom that will come from this; and how we can begin the process of forgiveness. Horrobin’s theological treatment of this vital but frequently under-emphasized facet of Christian living is generally right on, as is his practical advice. (A note: Horrobin also explicitly ties forgiveness to the physical healing of the forgiver; take that as you will.)
This is a short book with a clear emphasis on readability, and it features some of the presentation issues common to little books of this type. There’s Horrobin’s overuse of exclamation points, for one thing. There’s also the frequent points, repeated verbatim from the text for emphasis, presented in gigantic type, even in mid-sentence.
The Most Powerful Prayer on Earth is a brief but valuable and sufficiently overarching book on forgiveness, and serves well enough as a practical introductory guide to this extremely important subject.
