Passage
If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
John 15:5 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.
John 15:6 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.
John 15:7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
John 15:8 Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
John 15:9 As the Father hath loved me, so have I loved you: continue ye in my love.
The verse centers on "abide", "words", "shall", and "done". It is saying that the verse draws attention to "abide" and "words", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "If a man abide not in me..." into verse 8's "Herein is my Father glorified that ye...", so "abide" and "words" 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 "abide" and "words" with trust shaped by these words, not by a vague optimism outside the passage.
