I realize you asked this question of Deborah Sexton, but I will give you my two mites ~ you really have to continue reading from verse 8 to verse 12, which tells you WHEN tongues will cease. "For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known." This is speaking about the return of Christ.
Furthermore, continue on in Chapter 14, which tells us to "Pursue love, yet desire earnestly spiritual gifts, but especially that you may prophesy." It goes on to say how tongues are profitable and not profitable, depending on their use. They are used to edify oneself in private prayer (v. 4), and the body when interpreted (v. 5). Interpretation is also a gift (1 Cor 12:10; 14:13). So, as you can see, the Chapter before and after 13 show the context of the verse many use to say tongues have already ceased. That is not true. And to call the Holy Spirit (His gifts) of the Devil (unclean) is to borderline on the unforgivable sin (Mark 3:29-30).
