The term “heaven” also refers to the spiritual heavens, or spirit realm, a level of existence higher than and outside of the physical universe. (1 Kings 8:27; John 6:38) These spiritual heavens are occupied by Jehovah God, who is “a Spirit,” as well as by the angelic spirit beings whom he created. (John 4:24; Matthew 24:36) At times, “the heavens” are personified to represent the faithful angels, “the congregation of the holy ones.”—Psalm 89:5-7.
The Bible also uses “heavens” to refer specifically to the portion of the spirit realm where Jehovah actually resides, his “dwelling place.” (1 Kings 8:43, 49; Hebrews 9:24; Revelation 13:6) For example, the Bible foretold that Satan and the demons would be thrown out of heaven, no longer being allowed to enter Jehovah’s presence. However, they would remain in the spirit realm.—Revelation 12:7-9, 12.
