denominated spiritual.

This spiritual and divine light does not consist in any impression
made upon the imagination. It is no impression upon the mind, as tho
one saw anything with the bodily eyes: it is no imagination or idea of
an outward light or glory or any beauty of form or countenance, or a
visible luster or brightness of any object. The imagination may be
strongly imprest with such things; but this is not spiritual light.
Indeed, when the mind has a lively discovery of spiritual things, and
is greatly affected by the power of divine light, it may, and probably
very commonly doth, much affect the imagination; so that impressions
of an outward beauty or brightness may accompany those spiritual
discoveries. But spiritual light is not that impression upon the
imagination, but an exceeding different thing from it. Natural men
may have lively impressions on their imaginations; and we can not
determine but the devil, who transforms himself into an angel of
light, may cause imaginations of an outward beauty, or visible glory,
and of sounds and speeches, and other such things; but these are
things of a vastly inferior nature to spiritual light.

This spiritual light is not the suggesting of any new truths or
propositions not contained in the Word of God. This suggesting of
new truths or doctrines to the mind, independent of any antecedent
revelation of those propositions, either in word or writing, is
inspiration; such as the prophets and apostles had, and such as some
enthusiasts pretend to. But this spiritual light that I am speaking
of is quite a different thing from inspiration; it reveals no new
doctrine, it suggests no new proposition to the mind, it teaches no
new thing of God, or Christ, or another world, not taught in the
Bible, but only gives a due apprehension of those things that are
