Revelation 8:1 And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.
2 And I saw the seven angels which stood before God; and to them were given seven trumpets.
3 And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer it with the prayers of all saints upon the golden altar which was before the throne.
4 And the smoke of the incense, which came with the prayers of the saints, ascended up before God out of the angel’s hand.
5 And the angel took the censer, and filled it with fire of the altar, and cast it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
6 And the seven angels which had the seven trumpets prepared themselves to sound.
Now the beginning of the wrath of God is going to start and this is cause for the silence in heaven. There has only been praise before now and because all that are in heaven know that God is about release His wrath upon earth and man it causes everything and everyone to pause.The next angel now takes a censer filled with the prayers of saints, remember they ask God oh how long will You wait. Then the angel took the censer and filled it with fire from the alter of God and cast it to earth and it caused voices , lightnings, thundering, and earthquakes. This is kind of a warning for the people who have rejected the preaching of the gospel to get ready to face the judgement of God. Now the seven angels with the seven trumpets are about to sound.
