I've read several books on prayer, and this one was different. I'll let you weigh a few of the differences and decide for yourself if you should find the nearest library.
'The Circle Maker' is filled with light humor. Humor is not the foundation, and it does not hinder the message- it is the tone of the author.
There aren't methods, it itsn't a how-to, and there is no step-by-step formula presented. There are ideas. And stories. Many, many stories of prayers of all shapes and sizes answered. The author focuses on specificity as an important- and often missing- aspect of prayer.
The author is a masterful writer. The book is built out of stories, and Mr. Batterson invites the reader into them so smoothly. They leave images in your head, rather than phrases. Those stories of answered prayers will stick with me for quite some time; more inspiration for me to circle my own prayers and not give up on them, even after 'seventy years'. Because our God, He answers prayer.
