At the end of each 2000 year cycle there is a Jubilee of fifty years. Much of what is prophesied for the cycle happens in that final Jubilee. The timing is in God's Purview so the calendar rendering is not precise to the day always. That the Essene's calendar put Messiah in 32 AD is startling enough for me to trust their use of the calendar. That their prophecy names the Cycle of Grace we are now approaching the end of is also noteworthy. That they prophesied, hundreds of years before Jesus was even born, that the cycle of Grace would end with the second coming of Messiah should give even you pause.
The Rapture removal of the Body of Believers in The Christ is a real event which Jesus introduced in John 14, and Paul filled in many details for that event. It is going to happen. Count on it. Don't be here AFTER He removes His Believers who He has born from above in their spirit and to whom He has Promised to give a new body and soul for their eternally alive spirit where The Holy Spirit is abiding. Don't die in unbelief.
