John 15:1-6 (NLT)
The vine & the branches
[Jesus said] 1 “I am the true vine, and my Father is the gardener. 2 He cuts off every branch in me that bears no fruit, while every branch that does bear fruit he prunes  so that it will be even more fruitful. 3 You are already clean because of the word I have spoken to you. 4 Remain in me, and I will remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me.
5 “I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing. 6 If anyone does not remain in me, he is like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. 7 If you remain in me and my words remain in you, ask whatever you wish, and it will be given you. 8 This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples.
The Greek for prunes also means cleans.
TIME OF DAY:
No obvious light source or light direction. Even the fire doesn’t cast a glow on Jesus or the vines!
Jesus – the Vine
I did a Google search to find reference for grapes, vine leaves, seceteurs & flames.
This is a simple illustration, but notice that Jesus is about to cut off a branch that is not producing any grapes or even leaves! I wanted his expression to be slightly sad or upset, as I imagine He is not very happy about ever having to cut anyone off the vine!
