What does the Bible say about earthly wisdom?

Spirits of the first spiritual zone possess comparatively little spiritual information and knowledge that is remarkable. This, regarding the first spiritual zone, is also true to a less degree of the second and third spiritual zones.

Yet when you come into communication with the second spiritual zone, you suddenly sit up and take notice because some of the messages that come to you from this zone are remarkable and contain information that is of vital importance to the human race.

It is not from the living that you learn the secrets of life, but from the dead—from those who have passed over into the spiritual world, and who, having attained to a high point in their spiritual development in this new world, are able to see clearly and to understand and to convey some small part of their knowledge to a few highly developed spirits in human form who have especially sensitive intellects.
