It has often been said, by many a theologian, that Jesus' words, as portrayed in Matt, 24:15-22, to take just part of the "Olivet Discourses" (for the moment), imply a dual prophecy, involving Great Tribulation which was to fall upon initially the Jewish nation, at the time of the 1st Jewish - Roman War (66 AD - 73 AD) and then to fall upon secondly, at some future time, also to involve Great Tribulation, all nations, which many a religion/theologist, rightly or wrongly, believe will again involve another 7 year period.
66 AD - 73 AD
We know from the historical record that both Jew and Christian alike, particularly before 70 AD, fled Jerusalem to escape the pending Roman onslaughts, not to mention infighting amongst themselves (see Josephus' historical record, entitled "Wars of the Jews"). One would hope however, that they did not have to flee in the winter, or on a sabbath.
" But of that day and hour no one knows..." Matt, 24:36, NASB
If we move forward now to the above verse and even take it in conjunction with Rev, 16: 16, which incorporates the one time use of HAR - MAGEDON, a still future event, could we possibly be talking about one single day, which for all our prayerful sakes, one would hope does not fall in the winter, or on a sabbath.....
2 Peter 3:10; Matt, 24: 42-44; 1 Thess, 5:2
The above are just 3 references to the "Thief in the night" scenario, when Jesus is to come suddenly, after the so called "RAPTURE" has already taken place for the remainder of the "ELECT". Those remaining on earth will be a mixture of other believers in the "RANSOM SACRIFICE" and non-believers. Jesus will then thresh the nations lined up against the symbolic Israel -see Micah 4:11-13. The question here then, should be as to how long will this threshing take. If mortal beings were doing the threshing, it would obviously take a long time. But, as Jesus and his heavenly following will be doing the threshing, could it not be possible that it be done in one day ?? Compare 2 Kings 19:35....
Matt, 24:21...in relation to the sabbath
First century AD, pre Gentile nations, sabbath ramifications aside. When it comes to having to preserve one's well being, with a view to flight, in this present day's age, we can be assured that sabbath day restrictions, at least among the Gentile nations, will hardly be prohibitive, particularly as the modern day sabbath, being Sunday, in most instances, bears no relation to God's intended day, i.e. Saturday. It will therefore be like most any other day.
So what then are we to make of, V. 21, assuming for the moment, for argument's sake, that winter is not going to to be a major hindrance in the - most probably short lived (not even a season) - tribulation, pre 2nd Advent, factor - see Matt, 24:22.
If Har-Magedon, itself, is to be a single day event, to be led by the "KING OF KINGS, AND LORD OF LORDS" - Rev, 19:16, then how more ironic could it be, than to be on a Saturday. If GOD has already decided that Saturday is to be the day, then his anger may well be all the more compelling, and that, when all is said and done, may be the true reason why we should pray for "it" not to happen on this day of all days....
