'Wilderness' signifies something with little life in it, as described in the internal sense in Luke 1:80 'Wilderness' signifies somewhere there is no good because there is no truth. 'Wilderness,' as in Jeremiah 23:10, signifies the Word when it is adulterated.

(Reference: Arcana Coelestia 1927)

'Sufficiency' relates to the reception of good, because good is the spiritual nourishment of the soul, as natural food is the nourishment of the body.
