Where is G-d? Who is G-d? How is it possible for G-d to hide from existence, when He is existence itself? G-d isn't actually hiding, there is just a thick barrier blocking certain aspects from our consciousness. At the beginning, G-d's presence in the world was very great and He was only a little bit hidden. Once Adam sinned, however, he damaged things and G-d's overt presence began to shrink. The Messianic era will not be the same as the world before Adam sinned. Why not? What are the differences?
