Yes, spiritual battle is important, but so is physical battle.
Where would we be if Charles Martel had not won the Battle of Tours in 732? Probably not here today.
Or the Knights of St. John (Knights Hospitallers of Malta) who defeated the Turks in 1565.
The defeat of the Turks at Vienna in 1683. http://www.historytoday.com/walter-leitsch/1683-siege-vienna
And the Crusades to reclaim the Holy Land from the Moslems after they had conquered the Christians communities that had grown up in the Middle East and the lands of biblical Israel.
