I ran across this book several years ago. It is still one of my favorites on topic of disability.
"Same Lake Different Boat" by Stephanie Hubach, is a must read for everyone. Whether you know a friend or family member with any type of disability, or you just want to understand more about disability, this book has something for you.
It examines Bible concepts of disability, the emotions involved in dealing with it, and how to best minister to those in our churches who are disabled. It is interesting, personal and easy to read. I cannot recommend it highly enough!
