Most of us seem to think that it will be a very quiet occurrence when Jesus returns to this earth, and to get our point across, we would refer back to the scripture which says: The day of the Lord will come like a thief in the night……1 Thessalonians 5. However this scripture only means that, we know not when the Lord will come, just as we know not when a thief may break in. Instead of Jesus returning quietly, it will be a very loud and gloriously noisy occasion.

There will be trumpets…when they sound the dead in Christ will rise from their graves. We who are still alive, our bodies will change into perfection, never to decay again. This is based on 1 Corinthians 15:52

Can you imagine trumpets sounding so loud that they will wake up the dead! That will be some sound.
