The way modern "tongues" are used today by many Christians is not really analogous to the function of glossalalia in the Apostolic church. The Apostolic gift of tongues has no revelance in the church today. The reason is that the Spirit is no longer gifting people to speak in non-Hebraic languages in order to instruct the ethnoi (Acts 2), confirm his gifts to them (Acts 10, etc.), or manifest his judgment against the Jews by confronting them with foreign tongues/languages (Deut. 28:49; 32:19-22; Isa. 28:11, 12; 66:18; 1 Cor. 14:20-25). Carefully consider that string of texts, beginning with Deut. 28. These are the passages that make sense of what is happening in the Apostolic age as God deals with unbelieving Jews. He speaks to them in foreign, non-Hebrew "tongues." It's a judgment and a means of provoking them to jealousy.
But today the Jew-Gentile division is gone. The Bible has been completed and written in tongues (Greek). The Apostolic phenomenon of tongues have ceased. The need for the gift to speak miraculously in non-Hebrew tongues is not needed. There may be an anology between tongues and other forms of ministerial communication (preaching, teaching), but the analogy between what is called modern "tongues" and the NT gift is tenuous at best.
One has to come to grips with the purpose of tongues at the inauguration of the New Covenant era. Tongues are languages, more precisely, non-Hebrew languages. They were miraculously given to provoke the unbelieving Jews to jealously, according to explicit Old Testament prophesies (1 Cor. 14:20ff.; Deut. 28:49; 32:19-22; Isa. 28:11, 12; 66:18). One again, that list of passages.
Have you ever asked: Why were tongues so prominent in the church at Corinth? They seem to be the only community that has such an interest in tongues, where tongues have broken out with such publicity. It's because the church met right next door to the synagogue (Acts 18:7)! The "unbelievers" in 1 Cor. 14:22 are the stiff-necked Jews, not simply generic non-Christians. The context of Isa. 28, which Paul quotes in 1 Cor. 14, makes that pretty clear. Lot's of provocation going on there in Corinth! If that is the case, then perhaps one can see how tongues (=miraculously given non-Hebrew utterances) serve no purpose today. During the transition period (mainly from 30-70 AD, but also a bit beyond that) when God was forming a new international church and the unbelieving Jews were resisting that (as they did all through the Apostolic age), God provoked them to jealousy with these foreign tongues/languages. Every time anyone spoke in tongues in the book of Acts, for example, the Jews are in view somehow.
