John 15:1-15
I am the true vine, and my Father is the husbandman.
Every branch in me that bears not fruit he takes away: and every branch that bears fruit, he purges it, that it may bring forth more fruit.
Now ye are clean through the word which I have spoken unto you.
Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
I am the vine, ye are the branches: He that abides in me, and I in him, the same brings forth much fruit: for without me ye can do nothing.
If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.
If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
As the Father hath loved me, so have I loved you: continue ye in my love.
If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.
This is my commandment, That ye love one another, as I have loved you.
Greater love hath no man than this, that a man lay down his life for his friends.
Ye are my friends, if ye do whatsoever I command you.
Henceforth I call you not servants; for the servant knows not what his lord does: but I have called you friends; for all things that I have heard of my Father I have made known unto you.

In John 15, Jesus mentions branches that bear no fruit and branches that bear fruit (vs. 2) but Jesus says nothing about branches that bear fruit but then later stop bearing fruit.
When Jesus spoke these words in John 15, how many people at that time, prior to Him being glorified, had received the Holy Spirit and were baptized by one Spirit into one body? - "the body of Christ?" (1 Corinthians 12:13).
John 7:38 - He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water. 39 But this He spoke concerning the Spirit, whom those believing in Him would receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified. So "in me" is part of the metaphor of the vine, (in the vine) and not in the body of Christ under the New Covenant which was not yet fully established.
So in John 15, we see two kinds of connections with Christ as the vine (the merely cosmic which bears no fruit and the spiritual and vital which bears fruit). Without that vital union with Christ, there can be no life and no productivity. Those who profess to know Christ but whose relationship to Him is self-attached, He neither elected them, nor saved them, nor sustains them. Eventually, the dead self-attached fruitless branches are cut off.
