According to some Christians you can't be an effective, powerful witness unless you as a believer go on to get baptized in the Spirit after your conversion and speak in tongues. If you don't speak in tongues, you're only half baked, they think, and you have little power to witness to the world. I intend to show here that this is faulty theology, and it's a theology which creates an ungodly, unnecessary and prideful class structure within the Church.
