As important as the success on radio was the band's ability to tour nationally – the costs of which had been formidable in previous years. Unable to raise enough money for nationwide tours in support of its previous albums, Petra received another break when the band Servant invited it to open on its 1981–82 tour. Under Hollingsworth's tutelage, the band refined its live performances, its members dressing in camouflage to emphasize the spiritual warfare theme recalled by "Never Say Die"'s artwork, which featured an ocean war setting with an electric guitar doubling as an aircraft carrier. The tour turned "Never Say Die" into a commercial hit. In December 1981, it became the first Petra album to crack the "Billboard" Top 40 Inspirational LPs chart, debuting at No. 27, peaking at No. 7 in April 1982, and lasting on the chart through February 1983, more than 60 weeks after its debut.
