Hello gallenwalsh
Is it literally wine….?
From what I understand, Jesus says that the words He speaks are Spirit and Truth so for me, no, it cannot be that Jesus is referring to a literal vine, or physical fruit and wine, or even a literal time, but a "process" that is something
spiritual for each one of us individually and specifically. We know that Jesus Christ is the Vine and we are the branches and the fruit of His Spirit that we bear,
if we abide in Him, are those fruits of love, joy, peace, kindness, goodness, gentleness, faithfulness, patience and endurance. To understand, accept and apply, spiritual fits only with spiritual not literal to spiritual or spiritual to literal. That would be to put old with new or like mixing calk with cheese.
As I understand, The Kingdom of God “within’ could only happen when there was a death and subsequent inheritance that Christ Jesus came to fulfill and share with us. Just as Pentecost could only occur when Jesus went away to return as the Holy Spirit, only then could the conversion within begin. Ray expounds this aspect well in his writings.
As I believe, The Kingdom of God is still at hand and for some, it is “within”, wherein Jesus Christ the Vine, produces the fruit of His Spirit by which we are known if we abide in Him. No one can abide in Him unless God first drags us to Him and causes us by His Spirit to dwell in Him. The Kingdom of God is within only when and as God makes it so which until then, it remains at hand. No one can convert themselves without the Spirit of God.
The kingdom of God is at hand for many and only as God appoints, do little by little, individual by individual come to faith in experience to believe it is within and in so abiding in the gift of His Spirit, bear much fruit. Until then and after then, God controls all and everything.
I appreciate your question that provided the prompting to consider spiritual with spiritual and research the meaning as Jesus inspired in recognition and thanks for the Work of God and His Spirit. For some Christ has already returned and for others He is still on His way.
that too is the Work of God in progress.
