Passage
Herein is my Father glorified, that ye bear much fruit; and [so] shall ye be my disciples.
Herein is my Father glorified, that ye bear much fruit; and [so] shall ye be my disciples.
John 15:6 If a man abide not in me, he is cast forth as a branch, and is withered; and they gather them, and cast them into the fire, and they are burned.
John 15:7 If ye abide in me, and my words abide in you, ask whatsoever ye will, and it shall be done unto you.
John 15:8 Herein is my Father glorified, that ye bear much fruit; and [so] shall ye be my disciples.
John 15:9 Even as the Father hath loved me, I also have loved you: abide ye in my love.
John 15:10 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.
The verse centers on "glorified", "herein", "father", "bear", "much", "fruit", "shall", and "disciples". It is saying that the verse draws attention to "glorified" and "herein", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "If ye abide in me and my..." into verse 9's "Even as the Father hath loved me...", so "glorified" and "herein" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "glorified" and "herein" with trust shaped by these words, not by a vague optimism outside the passage.
