Speaking in tongues first occurred on the day of Pentecost when the apostles spoke in other languages to share the gospel. According to Paul, speaking in tongues is valuable when interpreted so others can understand, but useless otherwise. There were those with the gift of interpreting tongues so non-speakers could understand. While some argue tongues ceased, scripture does not conclusively say so. If the gift is active today, it must be intelligible, for communicating with others, and interpreted according to Paul's instructions. Millions continue experiencing this gift as evidence it continues.
