Passage
and the Comforter, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and remind you of all things that I said to you.
and the Comforter, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and remind you of all things that I said to you.
John 14:24 he who is not loving me, my words doth not keep; and the word that ye hear is not mine, but the Father's who sent me.
John 14:25 `These things I have spoken to you, remaining with you,
John 14:26 and the Comforter, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and remind you of all things that I said to you.
John 14:27 `Peace I leave to you; my peace I give to you, not according as the world doth give do I give to you; let not your heart be troubled, nor let it be afraid;
John 14:28 ye heard that I said to you--I go away, and I come unto you; if ye did love me, ye would have rejoiced that I said--I go on to the Father, because my Father is greater than I.
The verse centers on "all things", "Spirit", "comforter", "holy", "father", "send", "name", and "teach". It is saying that the verse draws attention to "all things" and "Spirit", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "These things I have spoken to you..." into verse 27's "Peace I leave to you my peace...", so "all things" and "Spirit" 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 "all things" and "Spirit" with trust shaped by these words, not by a vague optimism outside the passage.
