There is no second filling of the Holy Spirit. We're sealed by the Holy Spirit when we're saved. There's no second Pentecost for anybody.

There's so much over-emphasis on speaking in tongues in some of the Charismatic churches that they take it as the sign that you're saved. The vast majority of those that claim to speak in tongues are just babbling. They're deliberately faking it.

If speaking in tongues was a spiritual gift that was given today the way it was given then there would no way to silence it or to keep it hidden.

Nobody truly prophecies today. If they did, God would be exposing false doctrine in 90% of today's churches.
