'Presence of God' in the Bible

And there was an ocean, as crystal-clear as glass, in front of the throne. And at the center, surrounding the throne were four living beings, covered with eyes in the front and back of them. [Note: In view of Isa. 6:1-3 and especially Eze. 10:20ff, these "living beings" appear to be some special order of heavenly beings who inhabit the presence of God].

Then I saw the seven angels who stand in the presence of God; seven trumpets were given to them.

And the smoke and fragrant aroma of the incense, with the prayers of the saints (God’s people), ascended before God from the angel’s hand.

The sixth angel blew his trumpet; and I heard a single voice speaking from among the horns of the golden incense altar which is in the presence of God.

Then the twenty-four Elders, who sit on thrones in the presence of God, fell on their faces and worshipped God,

Then I heard a loud voice speaking in Heaven. It said, "The salvation and the power and the Kingdom of our God have now come, and the sovereignty of His Christ; for the accuser of our brethren has been hurled down--he who, day after day and night after night, was wont to accuse them in the presence of God.
