Lyrically, "This Means War!" took the implicit spiritual warfare theme that had been present in Petra's albums and tours since "Never Say Die" and emphasized it further. Although the album ended for good the band's longstanding tradition of featuring electric guitars as warcraft, its picture of a warrior on his knees complemented songs with titles such as "Get on Your Knees and Fight Like a Man", "All the King's Horses" and the title track, a rousing rocker backed by a marching drumbeat that addressed Satan as the preordained loser of the war he had declared against Christ and his followers.
