5. The Feast of Trumpets is the Day of the Last Trump
On the Feast of Trumpets, the prayer service includes a hundred blasts of the shofar with four sounds: Tekiah, Shevarim, Teruah and Tekiah Gedolah. Paul tells us when the last trump (Tekiah Gedolah) is sounded on the Feast of Trumpets, we will transform from life to eternal life.
In a moment, in the twinkling of an eye, at the last trump [Tekiah Gedolah]: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed (1 Corinthians 15:52).
6. Day That No One Knows (New Moon and New Year)
The Feast of Trumpets can occur after the 29th or 30th day of Elul, so no one knows the day or hour until the cresent moon appears in the late afternoon sky. Jesus tells us the day of the Rapture is the Feast of Trumpets.
But of that day and hour knows no man (Matthew 24:36).
7. Day of the Marriage Feast of the Lamb
The Feast of Trumpets is the traditional Jewish wedding ceremony which lasts for one week.
In my Father's house are many [rooms]: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there you may be also (John 14:2-3).
God tells us what is going to happen before it happens. This time He tells us that the Rapture occurs on the Feast of Trumpets which is the Jewish New Year. Since God told us the day of the Rapture but not the year, the four horses, seven trumpets and other events tell us important events that occur before
the Tribulation.
