The Open Door and Last Trump are on the Feast of Trumpets, which is a
shadow/prophecy of the Rapture.

Thus says the Lord GOD: The gate of the inner court that faces east shall be
shut on the six working days; but on the Sabbath day it shall be opened and
on the day of the new moon it shall be opened.
Ezekiel 46:1

Blow up the trumpet in the new moon, in the time appointed, on our solemn
feast day.
Psalm 81:3

Let no man therefore judge you in meat, or in drink, or in respect of an
holyday [festival], or of the new moon, or of the Sabbath days.
Colossians 2:16

Which are a shadow of things to come; but the body is of Christ.
Colossians 2:17

Open ye the gates, that the righteous nation which keepeth the truth may enter
in.
Isaiah 26:2

Open to me the gates of righteousness: I will go into them, and I will praise
the LORD:
Psalm 118:19

This gate of the LORD, into which the righteous shall enter.
Psalm 118:20

Then said Jesus unto them again, Verily, verily, I say unto you, I am the door
of the sheep.
John 10:7

I am the door: by me if any man enter in, he shall be saved, and shall go in
and out, and find pasture.
John 10:9

The Feast of Trumpets, on the new moon, is when the moon is turned to
darkness.  It is also "on a day or hour that no man knows" --which is an
expression referring to this feast (and to a Jewish Wedding)-- because the new
moon happens 29.5 days after the previous one, creating uncertainty of
whether it will fall on the 29th or 30th day after the previous new moon, which
is the first day of the month, thus the festival is traditionally celebrated for two
days just to be sure.

Speak unto the children of Israel, saying, In the seventh month, in the first
day of the month, shall ye have a Sabbath, a memorial of blowing of trumpets,
an holy convocation.
Leviticus 23:24

And in the seventh month, on the first day of the month, ye shall have an holy
convocation; ye shall do no servile work: it is a day of blowing the trumpets
unto you.
Numbers 29:1

Just as the Lord Jesus Christ fulfilled all the spring feasts, and on each day of
each feast, so too, will the fall feasts be fulfilled when Christ comes the second
time, and in order, and on each day of each feast.  The Feast of Trumpets
points to the rapture, the Day of Atonement points to Satan's defeat,
Tabernacles points to establishing the 1000 year kingdom.  Trumpets is on the
first, and Atonement is on the tenth.  Excluding the days of the Festivals
themselves, there are "seven days of Awe" or tribulation between
them...including, 10.

Fear none of those things which thou shalt suffer: behold, the devil shall cast
some of you into prison, that ye may be tried; and ye shall have tribulation
ten days: be thou faithful unto death, and I will give thee a crown of life.
Revelation 2:10

2 Thessalonians 2
: the Falling Away
The timing and order of these prophetic events:  Rapture, Revealing the
Antichrist, Signing of 7 year treaty starting the 7 year tribulation or Day of
the Lord:

Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and
by our gathering together unto him. (Rapture)
2 Thessalonians 2:1

That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by
word, nor by letter as from us, as that the day of Christ is at hand. [The day
of Lord Jesus Christ (click to see verses below) is tribulation, otherwise there
would be no reason to be shaken and troubled. See
1 Thessalonians 4:18
above; the rapture is comforting, not troubling
2 Thessalonians 2:2

Let no man deceive you by any means: for that day [tribulation] shall not
come, except there come a falling away [departure/rapture] first, and that
man of sin be revealed, the son of perdition;
2 Thessalonians 2:3

Who opposeth and exalteth himself above all that is called God, or that is
worshipped; so that he as God sitteth in the temple of God, shewing himself
that he is God.
2 Thessalonians 2:4

Do you not remember that when I was still with you I told you this?
2 Thessalonians 2:5

And now ye know what withholdeth that he might be revealed in his time. 2
Thessalonians 2:6

For the mystery of iniquity doth already work: only he who now letteth will
let, until he be taken out of the way. The Church at the rapture
2 Thessalonians 2:7  

And then shall that Wicked [the antichrist] be revealed, whom the Lord shall
consume with the spirit of his mouth, and shall destroy with the brightness of
his coming:
2 Thessalonians 2:8

In other words,

1.  I beg you by our rapture hope,
2.  That you don't worry if you hear (you have missed it) and that the
tribulation is at hand.
3.  Don't be fooled by people (who say the rapture/resurrection is already past)
[2Tim 2:18] Who concerning the truth have erred, saying that the resurrection
is past already; and overthrow the faith of some. The tribulation doesn't start,
until you are raptured first, which allows the man of sin (antichrist) to be
revealed.
4.  Who will, (3.5 years later according to Dan 9:27) sit in the temple as God,
as the abomination of desolation.
5.  Remember I told you this?
6.  Now you know that it is your presence that withholds the man of sin, so
that he will be revealed in due time.
7.  For the antichrist is working now only a little, because we restrain him as we
are here and pray, until the rapture, when we will be taken out of the way.
8.  And then the antichrist will be revealed, whom the Lord will destroy at the
second coming.

But the Lord is faithful, who shall stablish you, and keep you from evil. 2
Thessalonians 3:3

Watch ye therefore, and pray always, that ye may be accounted worthy to
escape all these things that shall come to pass, and to stand before the Son of
man.
Luke 21:36

Jewish Wedding (a theme of the Feast of Trumpets)
Bridal Chamber = Heaven
In my Father's house are many mansions: if it were not so, I would have told
you. I go to prepare a place for you.
John 14:2

And if I go and prepare a place for you, I will come again, and receive you unto
myself; that where I am, there ye may be also. John 14:3

In Italics above is an expression, used by the groom in a Jewish Wedding.   He
speaks this to the bride and then leaves to build an addition onto his father's
house before returning for his bride.  He returns for his bride in the middle of
the night, as a thief, at an hour she might not think, with a loud cry, saying
"Behold! The Bridegroom Comes!"  Entering the "bridal chamber/heavenly
mansion" is the start of the bridal week, and is shown in Isaiah, showing the pre
tribulation rapture with the resurrection preceding it:

Thy dead men shall live, together with my dead body shall they arise. Awake
and sing, ye that dwell in dust: for thy dew is as the dew of herbs, and the
earth shall cast out the dead.
Isaiah 26:19

Come, my people, enter thou into thy chambers, and shut thy doors about
thee: hide thyself as it were for a little moment, until the indignation be
overpast.
Isaiah 26:20

For, behold, the LORD cometh out of his place to punish the inhabitants of
the earth for their iniquity: the earth also shall disclose her blood, and shall
no more cover her slain.
Isaiah 26:21

Being "hid in the Lord's house, or heaven during tribulation" is also seen in
Psalm 27, which is read daily in the 30 days prior to the Feast of Trumpets.

One thing have I desired of the LORD, that will I seek after; that I may dwell
in the house of the LORD all the days of my life, to behold the beauty of the
LORD, and to enquire in his temple.
Psalm 27:4

For in the time of trouble he shall hide me in his pavilion: in the secret of his
tabernacle shall he hide me; he shall set me up upon a rock.
Psalm 27:5

And now shall mine head be lifted up above mine enemies round about me:
therefore will I offer in his tabernacle sacrifices of joy; I will sing, yea, I will
sing praises unto the LORD.
Psalm 27:6

The Church is the Bride of Christ

Husbands, love your wives, even as Christ also loved the church, and gave
himself for it.
Ephesians 5:25

For this cause shall a man leave his father and mother, and shall be joined
unto his wife, and they two shall be one flesh.
Ephesians 5:31

This is a great mystery: but I speak concerning Christ and the church.
Ephesians 5:32

For I am jealous over you with godly jealousy: for I have espoused you to one
husband, that I may present you as a chaste virgin to Christ.
2 Corinthians 11:2

The Rapture is likened to a wedding, and from the Bible, we know a wedding
lasts a week, we know the rapture will be pre tribulation. The scriptures define
a marriage as being a week long event.  (Bridal week) = (Tribulation week)
Regardless of when the feast is in these verses (not at the end), the time of
intimacy (the bride being with the bridegroom sealed away in the bridal
chamber) begins at the start of the bridal week, and this is what we look
forward to in the pre tribulation rapture. And if you read these accounts, you
will see that deception in the stories probably would not have happened if the
feast were held at the end of the week, as is depicted in Revelation 19.

Judges 14:1-18 ...And Samson made a feast there, as was customary for
bridegrooms. ...If you can give me the answer within the seven days of the
feast... She cried the whole seven days of the feast.

Genesis 29:22-28 ..So Laban brought together all the people of the place and
gave a feast. ... Finish this daughter's bridal week.

Matthew 25:1 Then shall the kingdom of heaven be likened unto ten virgins,
which took their lamps, and went forth to meet the bridegroom.
Matthew 25:2 And five of them were wise, and five were foolish.
Matthew 25:3 They that were foolish took their lamps, and took no oil with
them:
Matthew 25:4 But the wise took oil in their vessels with their lamps.
Matthew 25:5 While the bridegroom tarried, they all slumbered and slept.
Matthew 25:6 And at midnight there was a cry made, Behold, the bridegroom
cometh; go ye out to meet him.
Matthew 25:7 Then all those virgins arose, and trimmed their lamps.
Matthew 25:8 And the foolish said unto the wise, Give us of your oil; for our
lamps are gone out.
Matthew 25:9 But the wise answered, saying, Not so; lest there be not enough
for us and you: but go ye rather to them that sell, and buy for yourselves.
Matthew 25:10 And while they went to buy, the bridegroom came; and they
that were ready went in with him to the marriage: and the door was shut.
Matthew 25:11 Afterward came also the other virgins, saying, Lord, Lord,
open to us.
Matthew 25:12 But he answered and said, Verily I say unto you, I know you
not.
Matthew 25:13 Watch therefore, for ye know neither the day nor the hour
wherein the Son of man cometh.

At the end of the tribulation, people are in heaven (the bride, the Church), and
coming down out of heaven, because they have been there for 7 years.

And ye yourselves like unto men that wait for their lord, when he will return
from the wedding; that when he cometh and knocketh, they may open unto him
immediately.
Luke 12:36

And after these things I heard a great voice of much people in heaven [the
raptured], saying, Alleluia; Salvation, and glory, and honour, and power,
unto the Lord our God:
Revelation 19:1

Let us rejoice and exult and give him the glory, for the marriage of the Lamb
has come, and his Bride has made herself ready;
Revelation 19:7

it was granted her to be clothed with fine linen, bright and pure"--for the fine
linen is the righteous deeds of the saints.
Revelation 19:8

And the angel said to me, "Write this: Blessed are those who are invited to the
marriage supper of the Lamb." And he said to me, "These are true words of
God."
Revelation 19:9

And the armies which were in heaven followed him [the raptured] upon white
horses, clothed in fine linen, white and clean.
Revelation 19:14

Immediately after the tribulation of those days shall the sun be darkened, and
the moon shall not give her light, and the stars shall fall from heaven, and the
powers of the heavens shall be shaken:
Matthew 24:29

And then shall appear the sign of the Son of man in heaven: and then shall all
the tribes of the earth mourn, and they shall see the Son of man coming in the
clouds of heaven with power and great glory.
Matthew 24:30

And he shall send his angels with a great sound of a trumpet, and they shall
gather together his elect from the four winds, from one end of heaven to the
other.
Matthew 24:31

And ye shall flee to the valley of the mountains; for the valley of the
mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before
the earthquake in the days of Uzziah king of Judah: and the LORD my God
shall come, and all the saints with thee.
Zechariah 14:5

And Enoch also, the seventh from Adam, prophesied of these, saying, Behold,
the Lord cometh with ten thousands of his saints,
Judges 1:14

When Christ, who is our life, shall appear, then shall ye also appear with him
in glory.
Colossians 3:4

Interesting verse number:  12:12  12 is written all over New Jerusalem, and
there are 24 elders in heaven after the rapture in Revelation 4:1.

Rejoice then, O heaven and you that dwell therein! But woe to you, O earth
and sea, for the devil has come down to you in great wrath, because he knows
that his time is short!
Revelation 12:12

Yes, the Bride is in heaven, coming down out of heaven at the end of the
tribulation:

And I John saw the holy city, new Jerusalem, coming down from God out of
heaven, prepared as a bride adorned for her husband.
Revelation 21:2

And there came unto me one of the seven angels which had the seven vials full
of the seven last plagues, and talked with me, saying, Come hither, I will
shew thee the bride, the Lamb's wife.
Revelation 21:9

And he carried me away in the spirit to a great and high mountain, and
shewed me that great city, the holy Jerusalem, descending out of heaven from
God,
Revelation 21:10

Mt. Zion & New Jerusalem: God's bride.

But ye are come unto mount Sion, and unto the city of the living God, the
heavenly Jerusalem, and to an innumerable company of angels.
Hebrews 12:22

And I have put my words in thy mouth, and I have covered thee in the shadow
of mine hand, that I may plant the heavens, and lay the foundations of the
earth, and say unto Zion, Thou art my people.
