Heaven, the invisible realm
nThough travel to and from heaven is usually spoken of as ‘up’ and ‘down,’ this is not always the case.
nIn 2 Kings 6, Elisha prays that his servant may see that they are protected by an invisible heavenly army.  “And the LORD opened the eyes of the young man; and he saw, and behold, the mountain was full of horses and chariots of fire round about Elisha.”
