Thank you for entering the discussion and sharing points for additional consideration. I do have a couple of question, which does not surprise you, I am sure!
When we speak of "will" we must understand that the will is attached to (belongs to) the divine nature. Natures have wills, not persons. This applies whether speaking of God or human beings. Belonging to the person as a property is the "I", "Thou", "He", that is, the sense of self. So when the Son says, "I do the will of my Father" it is the Person, the "I", that does/acts. Try to keep in the mind this useful memory aid: Natures are, Persons do/act.
I agree with "natures are, persons do" but is there any difference or separation of will within the Godhead? I think not, for I believe the one purpose and will of God is the perichoresis that binds all the (decreed) actions of God into One revealed and salvific Truth.
And defining the distinctions within the Godhead, as personal properties, does not eliminate the problem of suggested
persons that must co-operate in order to remain on the same track as each other, does it?
IOW's defining the will, does not quite address the validity of suggesting necessity and requirements within the workings of God, in the same manner as synergism suggests is worked between God and mankind in regards to salvation.
If synergism, as we believe, does not work salvation on earth, why would it exist in heaven?
