Gino,You asked......If the 7 years begins and ends in the 7th month, does the abomination of desolation occur on Passover? Short answer...no.Using the chart I made of all the time intervals God gave us for the end times it showed the abomination of desolation occurring 41 months after the start of the seven year period. Assuming that God's two witnesses show up to start the 7 year period on the Feast of Rosh Hashanah due to the significance of two witnesses to that feast ....and that that feast falls in September (7th month)...... this would put the "set up" of the abomination of desolation as per my graph in February. Does this make sense scripturally? Yes, Jesus in Matt.24:20 gave a big hint to anyone who would listen that the abomination would be "set up" in winter on a Sabbath day.And as per my graph http://www.fivedoves.com/letters/june2013/johnb624-3.htm ....... one month later at the 42 month mark or 3.5 years into the 7 year period the antichrist will declare himself to be the one true God. This would be one month after the abomination is set up and would be on or near the Passover season depending upon the year.You asked........ if the beast would counterfeit the 3.5 years of Christ's ministry?It is sure looking that way. As per Rev.13 (and my graph) the beast (antichrist) would be 3.5 years into his ministry or 3.5 years into the 7 year period when he will then declare himself to be the one true God. Rev.13:5,6 And to prove to the world he is........ he will kill God's two witnesses that no one on earth were able to harm.Rev.13:7 I also believe that it's at this time (the day he declares himself the one true God) that the statue (abomination of desolation) he "sat up" in Jerusalem (in the holy place) one month earlier will begin to speak.Rev.13:15You asked......would there be a counterfeit death and resurrection by the beast at that same Passover season?There could very well be.........this beast with Satan's indwelling is going to pull out all the stops and leave no rock unturned in trying to convince the world he is indeed the one true God. And from what we know from scripture he will do a very good job of convincing people."All who dwell on earth will worship him, whose names have not been written in the Book of Life of the Lamb slain from the foundation of the world." Rev.13:8Blessings........John B
