Beating guns - important things to ponder (so they do not beat us!)
Format: Kindle
I recently read an early copy of this book (Feb 2019). Beating Guns presents a thoughtful view of guns in our country. Seems like a good overview of where we are and how we got there. I appreciate that the views are presented by (fellows) that have held guns, so that they are not an abstract concept but a reality to them. I would hope this book helps people see the issues perhaps with a bit more understanding, and that in turn may lead to dialogue between people to arrive at a less antagonistic situation. This topic is complicated; no one book can possibly cover all the angles and options, yet this book and this approach are a reasonable way to keep people thinking about solutions.

Read it. You'll like it.
Format: Kindle
This book is challenging. Mostly because it hurts. It hurts to see statistics. It hurts to see memorials of lives lost that didn't have to be. But for me, it hurts because we are to be kingdom people now and we've failed on the gun front. I'm in the process of taking a rifle that was used in suicide and turning into a tool for life. We need to do that. So buy the book. Read it. Wrestle with it. Then get to turning swords into ploughshares.
