Before we left Niger, I was reading this book by Richard Foster: The Freedom of Simplicity. I hadn't finished it, but didn't want to bring it to the US and then have to carry it back to Niger. Books are too heavy to carry if I don't really need it! I need to see if I can find it in the library here so I can finish it.
Anyway, I would recommend this book. By Simplicity he means getting rid of things in your life that prevent you from concentrating on what is most important. He talks about getting rid of things that cause us to live beyond our means physically. He doesn't say that "things" are wrong or that you have to live austerely. He does say that simplicity looks different for everybody but how we all need to hold things loosely.
Fresh Wind, Fresh Fire by Jim Cymbala describes how the Brooklyn Tabernacle grew from a handful of discouraged people to a huge, vibrant church. Jim Cymbala says people ask him all the time what the secret is to growing a big church. They want to copy his program and have a church like his. He says there is no secret. It has to be a work of the Spirit and the only advice he can give is to make prayer a priority. This was a timely reminder to me to keep praying and not give up when the church in Tera seems doomed to failure. God is still at work!
