Hollingsworth, the band's manager, made Petra's mission clear: The band is not in competition with other Christian bands. We feel we are competing with Journey, Styx and REO Speedwagon. We need to be aware of them, because the people who come to see Petra go to see those bands as well. We are being very naïve if we don't keep that in mind. We need to have a light system, sound system and presentation that will be competitive with those groups.

The synth-heavy rock record was a monster hit. Helped in part by a newly inked distribution agreement between Word and A&M that would give Petra and other Word-distributed bands placement in mainstream music stores for the first time, Beat the System sold more than 200,000 copies in four months, and by the end of the year, Billboard had certified
