John 15 is about producing fruit.
John 15 “I am the true vine, and My Father is the vinedresser. 2 Every branch in Me that does not bear fruit He takes away; and every branch that bears fruit He prunes, that it may bear more fruit.
takes away - gk airo - to raise, to lift up, to raise from the ground, to raise up, to elevate, to lift up.
The interpretation should read, every branch in me that does not produce fruit in me he lifts up.
Jesus is using a term well known to the people he is speaking to. A vine-dresser raises or lifts up branches which are on the ground and ties them up. so they are not suffocated and can then produce fruit.
He also shows the other thing these vine dressers do. He prunes them so they can produce more fruit. Part of the pruning process is to cut off specific branches in that area that is not producing fruit, because it is dead. and you take them and throw them into the fire. When God prunes us, he is taking dead parts of our life and cutting them off and burnign them, which allows us to produce more fruit.
3 You are already clean because of the word which I have spoken to you.
the word clean here in the greek - katharos - made pure, clean, spotless, unsoiled,
we are already purified Jesus is saying, we are cleansed as paul later says by the washing of water by the word..
4 Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me.
Again, proving that John 15 is about producing fruit. not salvation.
