I disagree with your interpretation, but I understand that there are multiple views on this parable. However, I have never heard of yours before;
Jeremiah 31:31-34 "Lo, days are coming, an affirmation of Jehovah, And I have made with the house of Israel And with the house of Judah a new covenant, Not like the covenant that I made with their fathers, In the day of My laying hold on their hand, To bring them out of the land of Egypt, In that they made void My covenant, And I ruled over them -- an affirmation of Jehovah. For this [is] the covenant that I make, With the house of Israel, after those days, An affirmation of Jehovah,
I have given My law in their inward part, And on their heart I do write it, And I have been to them for God, And they are to Me for a people. And they do not teach any more Each his neighbour, and each his brother, Saying, Know ye Jehovah, For they all know Me, from their least unto their greatest, An affirmation of Jehovah; For I pardon their iniquity, And of their sin I make mention no more."(YLT)
John 12:48-50 "He who is rejecting Me, and not receiving My sayings, hath one who is judging him, the word that I spake, that will judge him in the last day, because I spake not from Myself, but
the Father who sent Me, He did give Me a command, what I may say, and what I may speak, and I have known that His command is life age-during; what, therefore, I speak, according as the Father hath said to Me, so I speak."
Deuteronomy 18:18-19 "a prophet I raise up to them, out of the midst of their brethren, like to thee; and I have given My words in His mouth, and
He hath spoken unto them all that which I command Him; and it hath been -- the man who doth not hearken unto My words which He doth speak in My name, I require [it] of him."
John 15:1-4 "I am the true vine, and My Father is the husbandman; every branch in Me not bearing fruit, He doth take it away, and every one bearing fruit, He doth cleanse by pruning it, that it may bear more fruit;
already ye are clean, because of the word that I have spoken to you; remain in Me, and I in you, as the branch is not able to bear fruit of itself, if it may not remain in the vine, so neither ye, if ye may not remain in Me."
John 3:16 "for God did so love the world, that His Son -- the only begotten -- He gave, that
every one who is believing in Him may not perish, but may have life age-during."(YLT)
This is New Wine ...New Covenant... this is the Kingdom Gospel.
