Passage
`I will not leave you bereaved, I come unto you;
`I will not leave you bereaved, I come unto you;
John 14:16 and I will ask the Father, and another Comforter He will give to you, that he may remain with you--to the age;
John 14:17 the Spirit of truth, whom the world is not able to receive, because it doth not behold him, nor know him, and ye know him, because he doth remain with you, and shall be in you.
John 14:18 `I will not leave you bereaved, I come unto you;
John 14:19 yet a little, and the world doth no more behold me, and ye behold me, because I live, and ye shall live;
John 14:20 in that day ye shall know that I <FI>am<Fi> in my Father, and ye in me, and I in you;
The verse centers on "leave", "bereaved", and "come". It is saying that the verse draws attention to "leave" and "bereaved", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "the Spirit of truth whom the world..." into verse 19's "yet a little and the world doth...", so "leave" and "bereaved" 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 "leave" and "bereaved" with trust shaped by these words, not by a vague optimism outside the passage.
