From Pastor’s Desk:
Acts 2:4 All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.
Key phrase here is “as the Spirit enabled them.” If you have “learned” a language that you calling “tongues” by repeating after someone else, I have sad news for you. The baptism in, or infilling of, the Holy Spirit, as Pentecostal believe, is accompanied by the initial evidence of speaking in tongues, or a heavenly language.
The point is that tongues come with the infilling of the Holy Spirit and not the other way around. A genuine experience of speaking in tongues is given by the Holy Spirit and Him alone. If prompted by anything else or anyone else, there has not been an infilling.
