Paul Begley has an awesome video of all the sounds being heard.

And he quotes Jeremiah 25:31

These sounds, wherever they are coming from, however they are being made are ultimately being heard NOW and allowed by the Lord at this moment in time.   And why is this?   Because we are in the season for the rapture and the tribulation.   We all know the transit of Venus is coming 6/5-6/6/2012 (manchild of Revelation 12 passing the face of the Son's throne), we all know the sign of the Shepherd King coming for His maidens on 5/20/2012, and we all know that there is a TOTAL solar eclipse in Libra on 11/13/2012 which represents the great scales of judgment.   Not setting dates, because I really do not know what the proper time between the rapture and start of the first half of the tribulation is of the 1260 days.   Is there a gap of 6-9 months?   Could Ken Peters: I Saw the Tribulation where he said that the saints had an amount of time to spread the gospel this gap, when he said that after the lights came back at the rapture, that the antichrist was all over the television saying shortly we will have a new order?
