Here is, I think, a great article on this passage of Scripture in the Enrichment Journal. It is by my NT professor Ben Aker (now professor emeritus) at AGTS.
Here is an excerpt:
Pentecostals hold two fundamental positions regarding the nature of the gift of tongues based upon 1 Corinthians 14:1–5. One group believes that this gift is addressed to God and involves such things as prayer and/or praise. They believe that the one interpreting tongues should speak a praise or petition addressed to God. Tongues in this instance never contain a “message” to believers. Further, tongues are an inferior gift. W.G. MacDonald, a proponent of this position, recently summarized his view: “Glossolalia is always directed to God, and only to Him. In form,glossolalia is spoken or sung to Him. In content, biblical glossolalia consists of worship or prayer. It consists of praise or petition, thanksgiving or intercession. Because glossolalia is unidirectional to God, it cannot be an oracular utterance. Designed for individual edification, glossolalia when properly interpreted, rests at the bottom of the apostolic scale of gifts benefiting the congregation.”1
The other group believes that, like prophecy, the gift of tongues can also be a message directed to the church when accompanied by the interpretation, and that this gift of tongues is no more inferior than any other gift when appropriately manifested.
