To start, there is nothing more personal than the indwelling of the Holy Spirit. There is no hiding from Him, no secrets, no spinning. The indwelling is as personal as it gets.
The word ”revelation” is defined by the dictionary as: “an act of revealing or communicating divine truth” and ”something that is revealed by God to humans”.
When I use the term “personal revelation” I intend the above meaning, not the more theologically oriented definitions you have cited, i.e. that something is to be written for Scripture.
Nevertheless, when the Holy Spirit indwells He indeed brings the Scriptures to life – which you call “illumination”.
But that is not all, He also gives discernment in every situation – spiritual clarity to know Truth from fiction, right from wrong, etc. This is prophesy, insight. He also gives us foresight, understanding where a thing today will lead or something which we have yet to face.
He also uplifts our worship and petitions, rapturing us in the “here and now” to love God more fully than our conscious mind could ever allow. At this level we are worshipping God in Spirit and in Truth.
When I speak of “personal revelation” I am speaking of all these things.
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
kewl-the spiritual clarity discerns the flesh from the spirit, the corporael from the uncorporeal?
