'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].

And the smoke of the [burning] incense, [mingled] with the prayers of the saints, ascended from [the incense holder in] the angel's hand up to the presence of God.
