If that was intended for me, yes, I do definitely believe in Sola Scriptura, but you have to include ALL of the pertinent verses, not just
the one that supports your position. I posted this to you before but to no effect. Do you see the "and I in him"? Both conditions
have to be true for someone to bring forth fruit - only those chosen by God, is God "in" them, and thus, only they can satisfy both requirements to bring forth fruit.
[Jhn 15:5 KJV] 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.
Only those ordained by God, not everyone who claims to be a Christian, they alone bring forth fruit,
[Jhn 15:8 KJV] 8 Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
[Jhn 15:16 KJV] 16 Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and [that] your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you.
