Ed Welch has written an excellent short book about how to care for others while they are grieving. In the book, he covers how to respond wisely with wisdom, with compassion, and with humility. In each section, he gives real life examples of how people have cared well and cared badly. Then he walks us through how to care well by asking the reader practical, reflective questions. This is an excellent short book, which I would highly recommend. The book can be purchased here
