Isn't it said by St. John in the first century that the world is not large enough to contain all the books it would take to record all that Jesus has done?
Ask; if there is more essance of revelation aside from the written word then where is it?
No need to be coy, you are suggesting there is more revelation, where is it?
My point is that unles it agrees with the Bible you are shooting yourself in the foot. And this stuff of secret knowledge has plagued the church since early times when the gnostics were constantly strolling into the meetings and declaring God had revealed that they were God in some vision or dream or something. Much of the writings in the epistles that deal with false teachers are directed at the gnostic heresies.
So as long as we are talking about gifts of the spirit and revelation and dreamds and visions that do not deny or contradict what is written I think you are doing fine. The flesh and carnal mind are attracted to false dreams and visions because they almost always glorify the self, although some folks just find Lucifer to be erotic or otherwise attractive. Such people frighten me intensely since their wild devotion to those experiences can lead to all manner evil.
Let the Word of God be your strong tower and God's spirit can take you anywhere. But know that the proof is in the fruit.
And here is where I have alway been able to see the difference between true and false revelation and spiritual gifts, false gifts lead to the works of the flesh eventually
'Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these' Gal 5:19-21
So called spiritual insights that lead to the following along with a recognition of the Lordhsip of Christ are usually of God.
'But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness. self-control;' Gal 5:22
Howeve often we have to simply be patient and wait on the true nature of these things to reveal themselves (often we are waiting to assess the fruit of the life that spoke them as well.)
'The sins of some men are quite evident, going before them to judgment; for others their sins follow after. Likewise also deeds that are good are quite evident, and those which are otherwise cannot be concealed.' 1 Tim 5:24,25
We should let patience have it's perfect work while speaking the truth in love.
