There are those who believe that speaking in tongues ceased when the canon of Scripture (the Bible) was completed. Others, however, believe that this Spiritual gift is still in effect.  As to one's belief, it all depends on how they interpret what is written in (1 Corinthians 13:8-12).

Some interpret "perfection" spoken of in (1 Corinthians 13:10) to be a reference to the perfect word of God the Bible, while others believe it to be a reference to Christ Jesus. If one believes it to be a reference to the Bible, then their belief is that when the canon of Scripture was completed (the Bible) the Spiritual gifts of prophecy, tongues, and knowledge ceased (1 Corinthians 13:8). If one believes that it is a reference to Christ Jesus, however, then their belief is that these Spiritual gifts are still in effect and will be until the return of Christ Jesus. There is much debate as to which interpretation is correct.
