The Holy Spirit emphasizes the Right Priorities to the church at Corinth through the pen of Paul. They were to focus on Prophesying and be engaged in Instruction and Indoctrination for the saints. And if tongues were to be employed, the focus should be on Interpretation, and not the gift of tongues itself. Remember that the sign-gifts -tongues, prophesying, etc- were in operation during this period of the church's history.
