1 Thessalonians 5:1 "But of the times and the seasons, brethren, ye have no need that I write unto you."
Times in greek is "Chronos" and seasons means "Kairos" and it refers to the feasts and festivals. So the Thessalonians knew that Paul was referring to the feasts and festivals.
It is historically taught that on the feast of Trumpets the doors of Heaven are open and on Yom Kippur the doors close. Rev 4:1 "After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter."
Here we see a door open in Heaven (Feast of Trumpets/Yom Teruah) and the voice of a trump (last trump/trump of God) telling John to come up hither.
There are many more correlations between the Rapture/Jewish Wedding/Feast of Trumpets that without a doubt identifies what the last trump is and when it is blown. Coupled with the fact that the feast of Trumpets begins a new year.
Years come in groups of seven (just like days of the week). It is possible that we are in the sabbatical year and the new seven year cycle will begin in Sept 2015.
On the Jewish calendar a week always begins on the 1st day Sunday and ends on the Sabbath Saturday. If we are in the Sabbath year (last year in the cycle), then this feast of Trumpets 2015 could very well be the beginning of a new seven year period. Which means we may very well get to go home and the seven year tribulation will begin.
Keep in mind the seven year cycle must begin with the first year being after the seventh "sabbatical" year. Interesting info and again I encourage everyone to study the Rapture/Jewish Wedding/Feast of Trumpets. I have more Scriptures to support the Feast of Trumpets/Rapture and it really is a beautiful picture of our Messiah.
Note: The Four Blood Moons are a sign that war is coming for Israel. Will that war be what starts the seven year tribulation? Now, indeed only our Father knows that. Amen.
