Strength for Service to God and Country is a book of devotions designed for those in military service, firefighters, police officers, and others in service to their country. Such service can be life-changing for many courageous yet often under-recognized public servants. 

This new edition contains 365 devotions written by leading Protestant ministers in 1942, along with 40 new contributions from leaders of other faith groups, including Jewish, Islamic, and Roman Catholic. Over the life of this book, over one million copies have been purchased by and distributed to deserving service members.

Also available a Boys Scouts of America version and in the color khaki.
