The Lord has a purpose in tongues as He does all the other gifts listed in 1 Corinthians 12. Aren’t you glad He wants to speak to and through you in tongues? Tongues are given that we may speak forth a Holy Spirit inspired word then given the ability to know what He said by the gift (grace) of interpretation. While this may sound weird to many who will label it cooky or drunkenness as people did in the book of Acts, we don’t want to get calling a holy thing, an unclean thing. That would be considered blasphemy.
Tongues are for giving a message to others that differ in culture and language, to build you up as part of the church of Jesus, to cause you to worship, pray, war, and more in a heavenly language. Many have been baptized with evidence of speaking in tongues in their very own home, and some have had hands laid on them for this gift, while others have received it through a dream. Remember, the Lord does not pick and choose who can have this mighty gift. Ask for it, and if you don’t receive it right away, keep on holding on, it will come!
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
the interpretation of tongues. - 1 Corinthians 12:10
