'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.

154. CHANGES OF STATE OF THE ANGELS IN HEAVEN

By changes of state of the angels are meant their changes as to love and faith, and wisdom and intelligence therefrom, thus their changes as to states of life. States are predicated of life and of the things that are of life; and as angelic life is a life of love and faith, and of wisdom and intelligence therefrom, so states are predicated of these and are called states of love and faith, and states of wisdom and intelligence. How these states with the angels are changed will now be told.
