Acts 2

On the day of Pentecost -

"...suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance."  (New Testament | Acts 2:2 - 4)

I note that there were also there -

"....at Jerusalem Jews, devout men, out of every nation under heaven."  (New Testament | Acts 2:5)
"Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language.
7 And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilæans?
8 And how hear we every man in our own tongue, wherein we were born?"  (New Testament | Acts 2:6 - 8)

And as a result -

"...they were all amazed, and were in doubt, saying one to another, What meaneth this?
13 Others mocking said, These men are full of new wine."  (New Testament | Acts 2:12 - 13)

Obviously, miraculous signs never persuade all men.  Though there are many that believe this testimony that took place in the days of the early apostles.  It happened in modern day as the Kirtland Temple was dedicated where the Prophet Joseph Smith prayed -

"Let it be fulfilled upon them, as upon those on the day of Pentecost; let the gift of tongues be poured out upon thy people, even cloven tongues as of fire, and the interpretation thereof.
37 And let thy house be filled, as with a rushing mighty wind, with thy glory."  (Doctrine and Covenants | Section 109:36 - 37)

And shortly thereafter, the Prophet testified -

“A noise was heard like the sound of a rushing mighty wind, which filled the Temple, and all the congregation simultaneously arose, being moved upon by an invisible power; many began to speak in tongues and prophesy; others saw glorious visions; and I beheld the Temple was filled with angels, which fact I declared to the congregation. The people of the neighborhood came running together (hearing an unusual sound within, and seeing a bright light like a pillar of fire resting upon the Temple,) and were astonished at what was taking place. This continued until the meeting closed at eleven p. m.”

And a day or two later -

“I left the meeting in the charge of the Twelve, and retired about nine o’clock in the evening. The brethren continued exhorting, prophesying, and speaking in tongues until five o’clock in the morning. The Savior made His appearance to some, while angels ministered to others, and it was a Pentecost and an endowment indeed, long to be remembered, for the sound shall go forth from this place into all the world, and the occurrences of this day shall be handed down upon the pages of sacred history, to all generations; as the day of Pentecost, so shall this day be numbered and celebrated as a year of jubilee, and time of rejoicing to the Saints of the Most High God.” (Joseph Smith, History of The Church of Jesus Christ of Latter-day Saints, Vol. 2, pp. 428 and 432– 433.)

There will always be those that are amazed, those that doubt, and those that mock.
