Nowhere in Acts do you find the term "Baptism of the Holy Ghost" in connection with speaking in tongues.
The baptism of the Holy Ghost is related to salvation and not tongues (1st Corinthians 12:13).
There is NO command in the Bible to speak with unknown tongues.
A person who does not have the Holy Spirit is not saved (Romans 8:9 and 1st John 4:13).
A wicked generation seeks a sign (Matthew 12:39).
The tongues movement of today is NOT Acts 2 tongues, but the CARNAL tongues of 1st Corinthians.
The tongues of the Bible (in both Acts and 1 Corinthians) were always understandable, known, established, earthly, languages; not indiscernible sounds and utterances as used by the Charismatic Movement today in modern times.
God always initiated the miracle of tongues in the Bible, not men (Acts 2 and 10). In sharp contrast, men initiate the false tongues spoken in Pentecostal churches today.
The gift of tongues in 1st Corinthians was simply the usage of known languages, which some didn't understand, so Paul told them not to speak in foreign languages in multi-lingual congregations unless an interpreter is present. Notice that the gift of tongues in 1st Corinthians is different than the miracle of tongues in Acts 2. In Acts 2 Peter spoke in Greek, but at least 16 different nations heard each man in his own language.
