Dictionary.com defines the term Godless as:
I understand her concern for her sons exposure to others who may or may not use profane language, drink, carouse, etc ... however I know many, MANY godly people who see the military as a calling from the Lord and who have made a huge difference for the kingdom! Should we discount or discourage our children's calling because they make us uncomfortable? How is our military less needy of godly men and women and their families then the slums of Calcutta, Appalachia or some other mission field?
I can also say that God is on the move (hence my reference to Aslan in CS Lewis' books) in our military and in our Army and that the recently retired Chief of Chaplains was a true warrior for the Lord and a tremendous man of faith! I would also submit that God has used the military to teach me much about His character and love, challenged my faith and forced me to know what I believe and why, and given me faith-filled and faith-walking friends who are on fire for the Lord!
Whilst our military may not be able at times to acknowledge God the way we wish they are on the front lines both physically and spiritually these days and I can assure you that God is right in the midst!
