If you are looking for a quick, but incredibly powerful read, pick up Red Letters: Living a Faith that Bleeds. It is rare that I pass on a book after I am done, but I have already implored two co-workers to read it. And after you read it, I dare you not to live it.
I love that Tom Davis is able to admit his own human failings in this book. It doesn't feel like he is preaching to me, it feels like he is encouraging me. One of the most powerful parts of our trip to India (other than having my son placed in my arms), was visiting Mother Teresa's home. She never went into the streets of India without something to give to those asking for it. Tom makes the same statement. It is easy to tell people about Jesus. But it is much easier for people to believe in Jesus is you show them. Make their lives better, don't just show up, preach and leave them in the exact same situation as they started.
Tom reminds us that Jesus implores us to care for the widows and orphans, and of course you know that one of these causes is certainly close to our hearts.
Tom certainly practices what he preaches. Have any doubts? Follow his blog at http://www.cthomasdavis.com/

Another bonus of this book is that when you purchase it (available at amazon.com, barnes and noble and many christian bookstores), you feed an orphan for a month. Read it, love it, live it.
