"Strength for Service "was originally published in 1942, and over 720,000 copies were distributed to U.S. service men and women. After the events of September 11, 2001 the General Commission on United Methodist Men partnered with Evan Hunsberger, who had a vision to republish the little devotional book as his Eagle Scout service project to honor his grandfather. Eugene Hunsberger, a Navy corpsman, read it to dying men on the battlefields of the Pacific during World War II. This updated version includes 40 additional entries, with over one million copies purchased by and distributed to deserving service members.

Also available a Boy Scout version and in navy blue.
