5 I would that ye all spake with tongues, but rather that ye prophesied:
for greater is he that prophesieth than he that speaketh with tongues,
except he interpret, that the church may receive edifying.
Do you believe that the word tongue means some kind of gibberish?
No "tongues" can mean a Earthly language or a Heavenly language, just like at Pentacost when the Holy Spirit came upon the Disciples in the upper room like cloven tongues of fire, and then they went out and spoke to the crowd that had gathered outside because they heard this mighty rushing of wind and came to investigate, which gave them the opportunity to preach the gospel to them IN THEIR OWN TONGUES. In other words, all the different people who came from different places heard the message in THEIR OWN LANGUAGE.The other tongues is heavenly, and that's why Paul says when you speak in tongues you speak to God. Why would you speak to God in an Earthly foreign language when you can speak to him in your native tongue? It's because you are not speaking. It is the Holy Spirit who is speaking through you.
