Amen.
This is of faith, and if genuine when we pray we believe He hears, when we read the inspired written word we know it's True and when we walk in the spirit, it would mean our spirit is already quickened. (made alive)
Though many believe they have been made new and are in Christ, He never knew them.

I typed this out awhile ago but I believe the verse you bring up has more to do with the goat among sheep or wheat among tares.... the braches that bare fruit and those completely void of fruit....
I believe the timing of this lesson and Judas is important.
___________
John 15
1 I am the true vine, and my Father is the husbandman.
2 Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit.
3 Now ye are clean through the word which I have spoken unto you.
4 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.
5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
6 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.
Two sorts of branches
branches that bare fruit
"every branch that beareth fruit, he purgeth it, that it may bring forth more fruit"
"He that abideth in me, and I in him, the same bringeth forth much fruit"
and branches that do not bare fruit
"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"
"As the branch cannot bear fruit of itself"

I believe in me, would be those in the church, the body of Christ....
Some of which are not actually born again but have many supposed wonderful works to try to point to....
I believe these verses have absolutely nothing to do with a born again child of God, being thrown into fire...
