The messages sent through the Neviim by H'shem, to us were subject to time and place. If we are in this world He will direct us on what pertains to us in this world. Only those who walked among the angles as Yehoshua ben Yehotzadak did, were privileged to be spoken to about that world.
pg 443
Nefesh Hachaim
All physical elements of this world we perceive with our senses. H'shem is the life-force behind everything and imbues life into them. Since we can not see H'shem with our eyes we can only relate to Him with our intellect.
Gate Three, Chapter Five pg 113/114
