In our Communion with God He frequently Gives Revelation.
We ought to Pray for such.
The Spirit of Revelation implies that God Reveals in the Spirit.
The Spirit of Wisdom and Revelation signifies where God Reveals Himself and how He Imparts to us His Wisdom.
An impulsive thought is NOT to be interpreted as belonging to the Spirit of Revelation.
Only what we Intuitively Know of the Mind of God through the Operation of the Holy Spirit in our Spirit ever constitutes the Spirit of Revelation.
God Communes with us there and nowhere else.
