I am giving this book a Big Fat Zero. The very first paragraph of the 2nd chapter, in italics reads: Bold prayers honor God, and God honors bold prayers. God isn't offended by your biggest dreams or boldest prayers. He is offended by anything less.
NO. Ephesians 6:18 "Pray in the Spirit on all occasions with all kinds of prayers and requests.
1 Thessalonians 5:17 "Pray without ceasing..." Nowhere does the Bible say that you have to draw a circle, or a box, or a map, or a person, or anything for that matter. It just says to pray. And THAT is Biblical.
