I couldn't help but notice what Betty said about prayer and its impact on her life in her blog. That was really encouraging, Betty.
I just happened to finish reading this book on the subject of prayer. It didn't necessarily answer all my questions about prayer, but it was a pretty good discussion about the topic.
One of the main points I took from the book was how prayer can really change us, not necessarily our circumstances. I won't give away the whole book, but check it out if you're looking for a good book on prayer.
