Hebrews 8:5,6
"These men are offering sacred service in a typical representation and a shadow of the heavenly things; just as Moses, when about to construct the tent, was given the divine command: For He says: “See that you make all things after their pattern that was shown to you in the mountain.” But now Jesus has obtained a more excellent ministry because he is also the mediator of a correspondingly better covenant, which has been legally established on better promises."
The altar stands for God's will.
The bowls are used to transfer what is God's will into action.
Exodus 24:5,6
"After that he sent young Israelite men, and they offered up burnt offerings and sacrificed bulls as communion sacrifices to Jehovah. Then Moses took half of the blood and put it in bowls, and half of the blood he sprinkled on the altar."
In Revelation, the bowls of God's anger are representative of pouring out God's will for the religious institutions (Babylon the Great) and the governments in opposition to God (UN and associated nations).
Exodus 19:16-19
"On the morning of the third day, there was thunder and lightning, and there was a heavy cloud on the mountain and a very loud sound of a horn, and all the people in the camp began to tremble. Moses now brought the people out of the camp to meet the true God, and they took their place at the base of the mountain. Mount Siʹnai smoked all over, because Jehovah came down upon it in fire; and its smoke was rising like the smoke of a kiln, and the whole mountain was trembling violently. As the sound of the horn grew louder and louder, Moses spoke, and the voice of the true God answered him."
The sound of the horn or trumpet meant Jehovah was coming.
The trumpets in Revelation are symbolic of Jehovah's coming judgments on religious institutions (Babylon the Great) and the governments in opposition to God (UN and associated nations).
The plagues in Egypt were symbolic of God's adverse judgment on the religious and governmental institutions of Egypt. The plagues on Baal in Elijah's day were symbolic of God's adverse judgement on false religious institutions and those associated with them.
The plagues in Revelation are also God's judgments against the religious institutions (Babylon the Great) and the governments in opposition to God (UN and associated nations).
The visions of Revelation are not presented sequentially. They overlap and repeat and give details in slightly different perspectives.
When Jesus is enthroned in heaven, he is the one that will take the lead in executing God's will on earth. He is the one who directs the trumpets/plagues/pouring out of bowls. When Jesus takes the throne in heaven, he will begin his furious ride to accomplish God's will.
Zephaniah 1:14
"The great day of Jehovah is near!
It is near and it is approaching very quickly!"
Very soon, Babylon the Great will be as devastated as the empty church in this video...

And 3 1/2 years after that, all opposers of the God of Love will be removed - those who prefer the rule of the UN and God's chief enemy to the rule of God's king Jesus.
Habakkuk 2:2,3
"Jehovah then answered me:
“Write down the vision, and inscribe it clearly on tablets,
So that the one reading aloud from it may do so easily.
For the vision is yet for its appointed time,
And it is rushing toward its end, and it will not lie.
Even if it should delay, keep in expectation of it!
For it will without fail come true.
It will not be late!""
