What happens when two believers read the same scripture or hear the same word, yet disagree on its meaning? How is that resolved? How can it be an absolute?
BTW I think your definition is still too broad and does have more elements than Illumination. We have to be careful not to add extras to the word of God.
BTW I would say illuminations tend to be personal. If I tell you something that God has shown me, you may not see it..I think it depends on the spiritual maturity and needs of the hearer
Are you using the word Illumination as in quicken?
This would be a form of revelation or witnessing to!
The Holy spirit has an endless repertor of enlightment.
15 For thus saith the high and lofty One that inhabiteth eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.
