I don't rule out supernatural means, it's just beyond my limited understanding and research of this prophesy.
Isaiah 27:12–13 In that day the Lord will thresh from the flowing Euphrates to the Wadi of Egypt, and you, Israel, will be gathered up one by one. And in that day a great trumpet will sound. Those who were perishing in Assyria and those who were exiled in Egypt will come and worship the Lord on the holy mountain in Jerusalem.
Matt. 24:31 And He will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other.
We are told to watch the signs, not given a date. I have a hobby of watching seismic events and yesterday we had a 7.4 in Mexico followed by a 5.8 in CA a few hours ago and a 6.2 in Japan. But when discussing the trumpet, I noted a couple of months ago when the 5.7 rocked Salt Lake City, it knocked the trumpet out of Moroni’s hand on the Morman Tabernacle. The coming trumpet blast will come, and in my opinion, that is a sign that it’s not from Moroni. Sometimes God in not subtle.
