A while ago I picked up the book Terror-rest by Ed Morris. I finally got round to reading it, and it's worth it. He wrote it in the aftermath of the Lockerbie plane crash, 9/11, and 7/7 terror attacks to seek to defuse some of the fear following on from these events. How can people find safety in a world where they fear violence?
The book draws on Psalm 91 in the Bible, seeing its words as an invitation not just to people who would normally read the book, but to all those who would draw protection from God. The book is full of real life examples of people who have found an antidote to fear or violence, including some from the Armed Forces. (Psalm 91 is sometimes described as the Soldier's Psalm.) He looks in depth at each verse of the poem, so technically this is a commentary on Psalm 91 and a very readable one, and he encourages his readers to travel with him through the short book in small bites over a month. He's also set up a web site for comments from readers and more background at http://www.terror-rest.net/.
I haven't finished reading the book yet, so I may add to this article. However I'm already impressed by a sense of God's care and presence, and experiencing greater calm!
