The seals we are to place in our mind, (forehead) so when you see a seal opened as written come to pass, you will know that the Trumpet has sounded for that Seal. For example, the 2nd seal of wars and rumors of war we know the trumpet has sounded as we see in the Middle East and the World wars and rumors of war, even in the USA.
Rev 5:4   And I {John} wept much, because no man was found worthy to open and to read the book, neither to look thereon.
Rev 5:5   And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Judah, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.

Remember, Christ was the only one that could open the Seals.

Rev.6:7   And when he (Christ) had opened the fourth seal, I (John) heard the voice of the fourth beast say, Come and see.

 Rev.6:8  And I looked, and behold a pale  horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.

 Now I know this sounds scary, but you must realize that satan is death, and the only way he can "kill" is by his deception and lies with only a spiritual death to get you to follow him. It is a spiritual death because if you follow him it could lead to the death of your soul. Up in smoke forever.  1/3 of God's children followed satan in the first earth age and I believe they are living in the flesh now because look at the crazy laws and the World in general. Also look at the four hidden dynasties of Political, Economical,  Education, and Religion.

Death = (death) Strongs G2348 - thnēskō - to be spiritually dead only).  spiritually dead simply because you will follow the antichrist if you allow it by believing he is the true Christ.
He will only be able to kill with his lies because he wants company going into the lake of fire.  So he can, and will kill spiritually if you allow him by believing upon him and following him as the true Jesus Christ.  Remember, The devil is another role of satan for he plays many roles like the serpent in the garden for one.
hunger = What happens when a famine is upon us? A scarcity of harvest, for satan will have control of everything Political, Economical,  Education, and Religion. in his one World system.

 to kill with sword = satans lies as he will be the ruler in Jerusalem proclaiming that he is the true Christ, or any god that people worship like saying, follow me and I will give you anything, all the food you can eat, or pay off all your bills, etc. so on and on and on. Deception and lies about everything for your very Soul and that is his sword.
Christ also has a sword, a two edged sword which is His tongue that cuts both ways. The truth if you want to hear it, or a lie if you want to be deceived. It is all up to you.

The beasts are not the living beast that surrounds the throne of God, "the living ones".  The beasts are a venomous beast, thera {thay'-rah} in the Greek tongue which is a venomous asp, A serpent, another role of satan. Remember the serpent in the garden of Eden?  The one in the same.  So don't be deceived by satan and his systems for he will be head over the Political and Religious systems when he is cast to this earth.

How will satan come into power? "by peace shall destroy many". He will not be in red having horns looking like something out of a cartoon.
Dan 8:25  And through his (satan) policy also he shall cause craft to prosper in his hand; and he shall magnify [himself] in his heart, and by peace shall destroy many (spiritually destroyed thinking he is Christ): he shall also stand up against the Prince of princes (Christ); but he shall be broken without hand.  So this pale horseman is symbolic of death, and satan is death, and is already condemned
to death, but he can lead your soul to perish if you believe his lies and deceptions.

---

Hebrew 2:14  Forasmuch then as the children are partakers of flesh and blood, he (Christ) also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; (satan)
Just think of this for a moment.  Power is given to satan to rule over the Earth. His systems of Political to Religion will be powerful.
And hell followed, is the death of the soul. The end of existing forever. Not to fear, for satan is already condemned to death, and he will go into the lake of fire.
Eze. 28:18  Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
 Everyone that will have eternal life will see this happen.

Rev.20:6  Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
What does a Priest do? Teach, and in the one 1000 years there will be strict teaching. The first resurrection is yours, if you don't fall into the arms of satan at the sixth trump.
beasts of the earth - a person who possesses great power, as a sovereign, monarch, or ruler. Strong's G2339 - thēra - of preparing destruction for men. You are the prey.  "therion in the Greek,  A venomous beast, asp".  satan will kill with sword, (his mouth) with his sayings, like, Worship me, for I am Christ and I will give you everything if you worship me. So we have here, the systems of satan, preparing the way for the rider of the first white horse on the 1'st seal at the sixth trumpet.

I know you heard so many times that this world will end.  This earth age will end, not this earth. Our spiritual body will return as it was in the first earth age before the fall, (katabole) or rebellion of satan.
God created man in the flesh in the beginning of this 2'nd Earth age, and in the garden of Eden satan tempted, and won over Eve. Why?  To stop the seed line that Jesus Christ would come through.  satan tried again when, "THOSE WHO LEFT THEIR HABITATION," in Heaven and came to Earth to impregnate woman to stop the seed line of Christ again.  Their children were GIANTS, as you will read in the book of Jude below and in Gen. At their return, the lake fire for them. This is why God cause the flood in the time of Noah, and that was to get rid of all the giants from the fallen Angels that left their habitation in Heaven. God saved the seed line of Christ from being contaminated by causing the flood. satan always failed, but kept trying to stop Christ from being born of woman. However, he will try again when booted out of Heaven to make all mankind follow him.
 
Gen 6:1 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
Gen 1:2 And the earth {was} (should be became) void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
 ({was} = Strong's H1961 - hayah  -became, to happen, fall out, occur, take place, come about, come to pass,to come into being, become). the fall of satan as he tried to overtake Gods place.
Gen 6:3 And the LORD said, My spirit shall not always strive with man, for that he also [is] flesh: yet his days shall be an hundred and twenty years. (God cut the lifespan of man to 120 years)
Gen 6:4  There were giants (Strong's H5303 - nĕphiyl (giants, the Nephilim) in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare [children] to them, the same [became] mighty men which [were] of old, men of renown.
 
Gen 6:5  And GOD saw that the wickedness of man [was] great in the earth, and [that] every imagination of the thoughts of his heart [was] only evil continually.
Gen 6:6  And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
Gen 6:7  And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
Jude 1:4   For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord   God, and our Lord Jesus Christ.
Jude 1:5   I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
Jude 1:6   And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.

Gen 6:8  But Noah found grace in the eyes of the LORD.
So, if this seems strange to you or don't understand, don’t worry.  Just don’t worship satan and his systems when he returns at the 6'th trump, and read our father’s word as much as you can to gain knowledge.  Because If you listen to man and the way they teach you will never learn.  This is why so many people do not understand the Bible. God does not like it, and he is going to do something about it, you can count on it.
Jer 23:1 Woe be unto the pastors that destroy and scatter the sheep of my pasture! saith the LORD.

Do you realize that satan, The "anointed cherub that covereth" ( Ezekiel 28:14 ), was over the Throne of God at one time in the first Earth age? If satan would have never turned against God by wanting to take Gods place as God, we would have never been in these flesh bodies, and this second Earth age would not be.
Eze. 28:14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.
But satan wanted to be God, and this is why we are born of woman from the bag of water to go through this earth age in these flesh bodies, to choose good or evil, Christ or satan.
 
As far as satan, he cannot harm a hair on your head as written in Luke 21.  Believe it.
Luke21:18  But there shall not an hair of your head perish
Remember, God is your Heavenly Father.  Have you told him you loved him lately?  Because that is all God wants, your love.
Hos 6:6  For I desired mercy (love), and not sacrifice; and the knowledge of God more than burnt offerings.

Mark13 events of 4th seal

 Mar.13:9   But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: (Mind beaten with lies only for the elect) and ye shall be brought before rulers and kings for my sake, for a testimony against them.
When delivered up to satan or satans council you will only be mind beaten to try to make you worship him and his systems, but only 10 days. For whose sake?  The Lord's sake, Jesus Christ.

Mar.13:10  And the gospel must first be published among all nations.
And it will. When delivered up the elect will not speak, but the Holy Spirit of God will speak through them and this is how the Gospel will be published to all the World. Wait for the Holy Spirit to speak
thru you.

Mar 13:11  But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost.
If God's elect do not let the Holy Spirit speak through you or them. Or you, the elect do your own talking  to what you want to say, this is the unpardonable sin. "it shall not be forgiven him" (you).
I know I did not go in too much detail on this subject so if you have a question about this you can email me and I'll be glad to help you.
