Extending from Biblical analogies and characters used as role models [1] [2] [3][15] [4][16][17][18][19][20], the campaign uses narratives, metaphor and scripted staged presentations including images of weapons, pervasive use of a red pennant, and terms from a war lexicon such as "God's Army", "enemy" and "battle." It has used current and former members of the U.S. armed forces prominently in the Battle Cry stadium events, encouraging young people to become "the warriors in this battle." [21] In "Battle Cry for a Generation," a book released at the start of the campaign, Ron Luce wrote, "This is war. And Jesus invites us to get into the action, telling us that the violent — the 'forceful' ones — will lay hold of the kingdom." [22]
