Will the world hear a trumpet sound at the Rapture?
No, the world will not hear a trumpet sound at the Rapture. According to the teaching, the Rapture is a silent, instantaneous, unknown event; the world will not know believers have gone, and there will be no trumpet sound that the world hears.
Les teaches that at the Rapture it is going to be a silent, unknown event. The world is not going to know that believers have gone. It will be instantaneous and silent, and there will be no trumpet sound that the world will hear. This contrasts with the Second Coming, where after the tribulation the sign of the Son of Man appears in heaven, all the tribes of the earth mourn, and they shall see Him. At the Rapture, however, the world remains unaware.
