"I looked, and behold a door standing open in heaven... and behold, a throne was standing in heaven and One was sitting of the throne.
And I saw in the right hand of Him who sat on the throne a book... And no one in heaven, or on earth, or under the earth, was able to open the book, or look into it. I began to weep... and one of the elders said to me, '...the Root of David, has overcome so as to open the book...'
And I saw in the middle of the throne... a Lamb standing, as if slain... And He came, and He took it out of the right hand of Him who sat on the throne. And when He had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, having each one... golden bowls full of incense, which are the prayers of the saints."
Revelation 4:1, 2; 5:1-8
"And when He broke the seventh seal, there was silence for about a half an hour. And I saw the seven angels who stand before God; and seven trumpets were given to them.
And another angel came and stood at the altar, holding a golden censer; and much incense was given to him, that he might give it to the prayers of all the saints upon the golden altar which was before the throne.
And the smoke of the incense, with the prayers of the saints, went up before God out of the angel's hand. And the angel took the censer, and he filled it with the fire of the altar and threw it to the earth; and there followed peals of thunder and sounds and flashes of lightning and an earthquake."
"O Lord, I call upon Thee; hasten to me!
Give ear to my voice when I call to Thee!
May my prayer be counted as incense before Thee;
The lifting up of my hands as the evening offering."
Psalm 141:1, 2
"The end of all things has come near; therefore be of sound judgment for the purpose of prayer."
1 Peter 4:7
