If you are in the Son, then are disconnected from Him, you are disconnected from eternal life, and are gathered up and thrown into the fire, and poof, you are burned.
The passage you quoted says nothing about being "disconnected from eternal life".
Do you want to discuss the fact that the Truth of the Son will be with us forever or a passage that explains how branches can/cannot bear fruit?
John 15:4 (NASB) Abide in Me, and I in you. As the branch cannot bear fruit of itself unless it abides in the vine, so neither can you unless you abide in Me.
Inserting "eternal life" into a passage about bearing fruit seems more appropriate to another forum than one actually studying God's word.
But since you referenced the passage; We learn that wo different things are required to bear fruit from this passage:
1. You Abide in the Son
2. The Son abides in you.
#1 is covered "forever".
2 John 1:2-3 (NASB) for the sake of the truth which abides in us and will be with us forever: Grace, mercy and peace will be with us, from God the Father and from Jesus Christ, the Son of the Father, in truth and love.
John 15:3 (NASB) You are already clean because of the word which I have spoken to you.
We know from 2 John 2-3
and John 15:3 that having the Son abide in us, He does so forever and is cleansing (great point)! Thanks for showing how consistent God's word is.
The question is, do we "abide in the Son" (#2) and thus bear fruit or do we get "taken away"??? Indeed by the fire that's promised for all His branches (fruit bearing pruned ones or not):
John 15:2 (NASB) Every branch in Me that does not bear fruit, He takes away; and every branch that bears fruit, He prunes it so that it may bear more fruit.
John 15:6 (NASB) If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned.
Mark 9:49-50a (NASB) “For everyone will be salted with fire. Salt is good
