I agree with your point about context...but I can't agree the Trumpets are still future. Jesus gave the prophecy of them, as well as the Churches and Seals, while He was in the Holy Place, which is before He moves into the Most Holy Place and begins cleansing the Sanctuary.
Daniel 8 says "after 2,300 Days, then shall the Sanctuary be cleansed" and we know that these are symbolic days because the 70 Weeks - which virtually all agree are symbolic for 490 years - cannot be "determined" which means "cut off" or "amputated" from 2,300 literal days, but certainly can be cut off from 2,300 symbolic days, or literal years. The starting point for both the 2,300 and the 70 is 457 B.C., which means Jesus moved into the Most Holy Place in 1844. So, the Churches, Seals, and Trumpets are all parallel prophecies which begin in the 1st century when John saw the vision and when Jesus was ministering yet in the Holy Place.
The 5th Trumpet is the rise of Islam in the 7th century, which swarmed over the West and covered almost the exact migration area of the annual locust swarm, and is evidenced by other symbolism (ie., their power was in their ["horses'] tails", which is the flag of Islam).
The books of the Prophets are coded. The book of Daniel was sealed, the book of Revelation was sealed as well. Revelation is a book that has revelations that seemingly are unveieled yet they are written in Prophetic language. Thus as was written, both Daniel the Great Prophet, and John the Beloved, sealed the writings by coding what they were saying.
The WORD of GOD is Spiritual, and Life giving. There are 7 Angels of the 7 Churches. And those Angels were coded when speaking of the Great Men of GOD sent to lead the entire population of the children of the kingdom in the earth at that time. They were called Angels, becasue they were the ONLY ones that could hear from GOD. and did hear from GOD directly at that time. Thus, they are as follows"
Enoch, Noah, Abraham, Moses, Joshua, Apostle Peter, The Son of Man.
Each of these Angels of the Churches, had a message that they were sent to deliver to the people.
Enoch preached the Gospel of transgfiguration - and he transfigured in life without ever dying at all.
Noah preached the Gospel of the washings of regeneration, and he coupled an ARK that saved Mankind from extinction from the flood.
Abraham preached the Gospel of circumscision
Moses preached the Gospel of Atonement - And he brought the Law. Moses is the Law, a witness that testifies of GOD.
Joshua preached the Gospel of Revelation, and by revelation he brought down the walls of Jericho.
Apostle Peter preached the Gospel of the remission of sin.
The Son of Man preached the Gospel of immoratlity + incorruptibility.
These are the 7 Angels of the 7 Churches written of in Rev 1-3....
Each of these Angels of the Churches that has his message is also what was called "A Trumpet" . When Enoch was in the earth, and he was preaching his message, he was sounding a trumpet. Same with Noah, it was a trumpet, and the rest of them as well. Their messages are referred to as trumpets. The reason is because their messages reaps the children of the kingdom from the tares. That every child of the kingdom in the earth at that time, must hearken to him, and be led by him, to run their race. And here is a proof that Noah is the second Angel of the Church, one plain enough to see that wasn't really coded.
Rev 16
3 And the second angel poured out his vial upon the sea; and it became as the blood of a dead man: and every living soul died in the sea.
The 7th Angel of the 7 churches is the Son of Man that is to come, who Jesus His Pre-Eminence called "The Spirit of Truth', The comforter; and he was called the restituioner of all things, he was called the good samaritan, the stone hewn without hands, he was called the finisher, the one who got the job done, he was called Elijah by Malachi, he was called the Prophet by Apostle Peter, And He was called "another voice from heaven" in Revelation 18:4, because the message he has for the children of the kingdom is different to what every other preacher is saying in the earth Proving he is an Elijah- Just as Elijah of Tishbe was preaching a different message to the people than the prophets of baal, and Elijah John the Baptist preached a different message from the pharisees. And his message shall reap the children of life, and bundle the tares as chaff to be cast into the lake of fire - that is to say, reveal who the wheat and tares are. And his message will put on the wedding garment, preparing the bride for her wedding, for the second coming of Jesus His Pre-Eminence to receive, and she shall be an immortal bride, that conquered death, and proved she loved GOD.
And all the children of the kingdom that did not hearken to his message, that did not put on the wedding garment in life alive and therefore were told to leave the wedding, that did not conquer death in life by immortalisation in life, by bringing down the walls of mortality; bringing down the building blocks of mortality adumbrated in Joshua bringing down the walls of Jericho, all the children of the kingdom that do not complete their race, shall be cut off from among the people- which means they will die in this earth, and go to Abrahams Bosom where they will be resurrected at the second resurrection, and therefore shall not eat from the tree of life but shall inherit the New Salem. While those that immortalised in life shall gain entrance into Eden, the heavens world for Mankind.
THIS IS A TRUMPET
COME OUT OF HER
