Hey Dan,
Lee from Florida here. Coming from a Military family and having been a soldier myself, I know what you are feeling with his deployment. I've watched family members deploy and felt that same knot. I've deployed and felt a different knot. lol The good news is this. With the safety zone that has been established in the Bahrain area, a soldier is at least 10 times more likely to get harmed back in the grand ole U.S. while making a routine trip to the grocery store. He made it through plenty of those "grocery store deployments", he will make it through this one too. I know that statistic is easy to say but hard to apply, which is why terrorism is so effective even though it is .5% action and 99.5% propoganda.
Hope that made sense.
As a Veteran I have a special burden in my heart for soldiers and as a Pastor I will add him and your/his family to my congregation's Military prayer list.
As far as your pain, I hope you feel better quickly.
Lord, please touch Dan.
Lee from Florida
