Be careful about becoming overconfident with the devil. For example, don't be so arrogant as to believe that you are introducing me to God.
Maybe you're telling me about your understanding of Him, fine. Maybe you're Mephistopheles on the internet trying to divert me away from God with your "speaking in tongues."
Proverbs 15 has plenty of advice for us.
And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance. Acts 2:1-4
For they were hearing them speaking in tongues and extolling God. Then Peter declared, Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have? Acts 10:44-47
And when Paul had laid his hands on them, the Holy Spirit came on them, and they began speaking in tongues and prophesying. Acts 19:6
Pursue love, and earnestly desire the spiritual gifts, especially that you may prophesy. For one who speaks in a tongue speaks not to men but to God; 1 Corinthians 14:1-5
So, my brothers, earnestly desire to prophesy, and do not forbid speaking in tongues. But all things should be done decently and in order. 1 Corinthians 14:37-40
