Passage
But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and will remind you of all that I said to you.
But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and will remind you of all that I said to you.
John 14:24 He who doesn’t love me doesn’t keep my words. The word which you hear isn’t mine, but the Father’s who sent me.
John 14:25 I have said these things to you, while still living with you.
John 14:26 But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and will remind you of all that I said to you.
John 14:27 Peace I leave with you. My peace I give to you; not as the world gives, give I to you. Don’t let your heart be troubled, neither let it be fearful.
John 14:28 You heard how I told you, ‘I go away, and I come to you.’ If you loved me, you would have rejoiced, because I said ‘I am going to my Father;’ for the Father is greater than I.
The verse centers on "all things", "Spirit", "counselor", "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 "I have said these things to you..." into verse 27's "Peace I leave with 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.
