Wasted Prayer by Greg Darley; Know when God wants you to stop praying and start doing.
The basis of this book is great. Sometimes, we use prayer as a way to procrastinate. We feel God calling us to do something, to change something in our life, but we say "I'll pray about it" and keep putting it off. When we really know that we've already been told the answer. I think we are all guilty of that.
This book goes in depth on why when we know (and we all know when we just know!) what to do that we need to just do it! There are a lot of verses and stories to help us see how God sometimes commands us to act instead of pray.
I did feel like a book on this topic was a lot. I couldn't get into the whole book as I felt like I got the gist of it all within the first few chapters. The rest seemed to just reiterate what the beginning said.
