There are four angels mentioned in the Bible: Gabriel, Michael, Apollyon, and Lucifer. Two are holy and two are evil.
Apollyon and his role is described in Revelation 9:6-12:
And in those days men will seek death
and will not find it;
they will long to die,
and death flees from them.
The appearance of the locusts
was like horses prepared for battle;
and on their heads
appeared to be crowns like gold,
and their faces were like the faces of men.
They had hair like the hair of women,
and their teeth were like teeth of lions
They had breastplates of iron;
and the sound of their wings
was like the sound of chariots,
of many horses rushing to battle.
They have tails like scorpions,
and stings; and in their tails
is their power to hurt men for five months.
They have as king over them,
the angel of the abyss;
his name in Hebrew is Abaddon,
and in the Greek he has the name Apollyon
The first woe is past; behold,
two woes are still coming after these things.
Apollyon is the king of the bottomless pit and leads demons out to torment men for 5 months during the Day of the Lord This section of scripture only describes element of wrath.
The Day of the Lord also includes other elements. But we are only focusing only its context with the angels.
Apollyon is let loose out of the pit at the sound of the fifth trumpet, one of a series of 7 trumpet judgments of God.
God sends Apollyon as part His judgment after He returns and cuts short the Great Tribulation (Satan’s time of wrath on Earth).
Jesus has already gathered his church from the four corners the Earth; the dead rising first, and the remaining elect gathering together to meet Him in the air.
The rapture of the church must happen before God’s wrath is poured down because, “we are not appointed unto wrath.”
Here is where Jesus discusses His return and the gathering of His elect before the pouring down of His wrath.
When ye therefore shall see
the abomination of desolation,
spoken of by Daniel the prophet,
stand in the holy place,
(whoso readeth, let him understand)
Then let them which be in Judaea
flee into the mountains:
For then shall be great tribulation,
such as was not since the beginning of the world
to this time, no, nor ever shall be.
And except those days should be shortened,
there should no flesh be saved:
but for the elect’s sake those days shall be shortened.
Wherefore if they shall say unto you,
Behold, he is in the desert;
go not forth . . . believe it not.
For as the lightning cometh out of the east,
and shineth even unto the west;
so shall also the coming of the Son of man be.
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:
And then shall appear
the sign of the Son of man in heaven . .
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 24:15-21-29, 31
Michael appears to be immensely powerful crowned as a prince and an archangel. He is perhaps the greatest of all angels in heaven. One day we will find out.
The onset of the Great Tribulation is listed as the last time that he plays a role. It is highly likely that Michael is the force that withholds the Antichrist, allowing Satan to have his time to persecute the church for 3 1/2 years.
And at that time Michael shall stand up,
the great prince which standeth
for the children of thy people:
and there shall be a time of trouble,
such as never was
since there was a nation
even to that same time:
and at that time thy people shall be delivered,
every one that shall be found written in the book.
~ Daniel 12:1
This is the only scripture that points to what restraineth the Antichrist and allows his release, initiating the 3 1/2 year period known as the Great Tribulation (of Satan’s wrath).
I have found no biblical supports for another restrainer (popularly believed to be the Holy Spirit).
Nor is there any scripture to indicate that Michael is not the restrainer.
Scripture records Michael battling demons and Satan. It also reveals the fact the believers (by nature have the Holy Spirit) are still on Earth during the Great Tribulation.
This is the best interpretation of the restrainer of Satan I can find in scripture.
But the prince of the Persian kingdom
resisted me twenty-one days.
one of the chief princes, came to help me,
because I was detained there
with the king of Persia.
~ Daniel 10:13
The next rather long segment of scripture shows Michael ovecoming Satan and all his angels, casting them to Earth, and releasing them for the Great Tribulation to persecute the church who hold the testimony of Jesus.
Then war broke out in heaven.
Michael and his angels fought against the dragon,
and the dragon and his angels fought back.
And prevailed not;
neither was their place found any more in heaven.
And the great dragon was cast out,
that old serpent, called the Devil, and Satan,
which deceiveth the whole world:
he was cast out into the earth,
and his angels were cast out with him.
And I heard a loud voice saying in heaven,
Now is come salvation, and strength,
and the kingdom of our God,
and the power of his Christ:
for the accuser of our brethren is cast down,
which accused them before our God day and night.
And they overcame him by the blood of the Lamb,
and by the word of their testimony;
and they loved not their lives unto the death.
Therefore rejoice, ye heavens,
and ye that dwell in them.
Woe to the inhabiters of the earth
and of the sea!
for the devil is come down unto you,
having great wrath,
because he knoweth that he hath but a short time.
And when the dragon saw
that he was cast unto the earth,
he persecuted the woman
which brought forth the man child.
And to the woman were given two wings
of a great eagle,
that she might fly into the wilderness,
into her place,
where she is nourished for a time,
and times, and half a time,
from the face of the serpent.
And the serpent cast out of his mouth
water as a flood after the woman,
that he might cause her
to be carried away of the flood.
And the earth helped the woman (Israel),
and the earth opened her mouth,
and swallowed up the flood
which the dragon cast out of his mouth.
And the dragon was wroth with the woman,
and went to make war
with the remnant of her seed (the church),
which keep the commandments of God,
and have the testimony of Jesus Christ.
~ Revelation 12:7
Above, at the casting out of the Devil and his angels to Earth, scripture immediately refers to God’s children giving up their lives; while they overcame him (the Devil and his works of sin) by the blood of the lamb and the word of their testimony.
It becomes very clear that angels play a significant role in the salvation of God’s people, their chastisement, and the judgment of the wicked.
The second (good) angel mentioned in the bible is Gabriel. He primarily functions as a messenger, i.e., imparting wisdom to Daniel and pronouncing special messages to others such as telling Zacharias about the birth of his son, John the Baptist and Mary of the birth of her son, Jesus.
And Zacharias said unto the angel,
Whereby shall I know this?
for I am an old man,
and my wife well stricken in years.
And the angel answering said unto him,
I am Gabriel,
that stand in the presence of God;
and am sent to speak unto thee,
and to shew thee these glad tidings.
~ Luke 1:18-19
And in the sixth month
the angel Gabriel
was sent from God unto a city of Galilee,
To a virgin espoused to a man
whose name was Joseph,
of the house of David;
and the virgin’s name was Mary.
And the angel came in unto her,
and said, Hail,
thou that art highly favoured,
the Lord is with thee:
blessed art thou among women.
~ Luke 1:26-28
The fourth angel, Lucifer, gets his own post here since there is to much context to consider.
We can be confident that the angels have as much interest in learning about us as we do them.
God’s creation is most fascinating, wondrous, and awesome to them as well!
A Living Hope
We have a living hope that our O.T. Fathers deeply wanted to know more of, and that the angels still desire to see how the grace of God works in the lives of those who love Him.
Our salvation is precious and far above all things. Let us seek Him dearly as He asks.
Blessed be the God and Father
of our Lord Jesus Christ,
which according to his abundant mercy
hath begotten us again unto a lively hope
by the resurrection of Jesus Christ from the dead,
To an inheritance incorruptible,
and that fadeth not away,
reserved in heaven for you,
Who are kept by the power of God
through faith unto salvation
ready to be revealed in the last time . . .
Of which salvation
the prophets have inquired
and searched diligently,
who prophesied of the grace
that should come unto you . . .
which are now reported unto you
by them that have preached the gospel
unto you with the Holy Ghost
sent down from heaven;
which things the angels desire to look into.
~ Peter 1:3-5, 10, 12
