well you are wrong again
tongues are both a sign AND a gift as I stated
in first Corinthians 12 we read where they are described as a gift:
10 to another the working of miracles, to another prophecy, to another the ability to distinguish between spirits, to another various kinds of tongues, to another
fthe interpretation of tongues. I Corinthians 12:10
maybe pay more attention to everything the Bible says regarding tongues instead of just the parts you
think supply your understanding
