The genuine gift endowed a person with the miraculous ability to speak in unlearned foreign languages for the sake of proclaiming the Word of God and authenticating the gospel message. When used in the church, it had to be translated so other believers could be edified by the message. By contrast, the modern charismatic version consists of nonmiraculous, nonsensical gibberish that cannot be translated. It is a learned behavior that does not correspond to any form of authentic human language. Rather than being a tool to edify the church, contemporary charismatics use the fabrication as a private “prayer language” for the purpose of self-gratification. Though they justify their practice because it makes them feel closer to God, there is no biblical warrant for such unintelligible babble. It is a false spiritual high with no sanctifying value. The fact that modern glossolalia parallels pagan religious rites should serve as a dire warning of the spiritual dangers that can be introduced by this unbiblical practice.
