Only the apostles and some of those converted by their ministry spoke in tongues. The gift of healing is similar. With the progression of the testimony in the book of Acts, the number of signs and miracles diminishes quickly. Studying the book of Acts more closely, observe that signs and wonders are not repeated, but occur only when the gospel is presented for the first time. In fact, Jerusalem is the only place where multiple miracles are recorded.
Scripture presents two cases when signs and wonders take place.
Most commonly they are characteristic for the very beginning of a new dispensation. By way of exception they also occur as a unique and temporary testimony to warn the professing people of God of soon-coming judgments. Moses, Joshua, our Lord, the twelve apostles and the seventy that were sent out, were only sent to Israel and would fit in the first category, whereas Elijah and Elisha fit in the second category. The past testimony of signs and wonders, at the beginning of the Christian era, as well as a future testimony after the rapture of the Church, takes place within the borders of the Roman Empire. In Acts 2 and 19, and also in Corinth, the Jews are addressed by different tongues.
