Do you have congregational friends in the service? Do you send them gift boxes? You should! Did you know that Concordia Publishing House has an Armed Forces Devotional Book for about $5? It's really cool! It has appropriate scripture, hymns, prayers, and other things. What a great gift to give someone who is separated from their church family to help support their faith!
So, get your people together and when you send a gift box out to those in the service (and you should!) make sure this book is in it. If possible, have members of the congregation sign it and add a positive comment.
