Prayers of the saints

Revelation 8

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 the fire of the altar, and cast it upon the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
