Passage
`All things, as many as the Father hath, are mine; because of this I said, That of mine He will take, and will tell to you;
`All things, as many as the Father hath, are mine; because of this I said, That of mine He will take, and will tell to you;
John 16:13 and when He may come--the Spirit of truth--He will guide you to all the truth, for He will not speak from Himself, but as many things as He will hear He will speak, and the coming things He will tell you;
John 16:14 He will glorify me, because of mine He will take, and will tell to you.
John 16:15 `All things, as many as the Father hath, are mine; because of this I said, That of mine He will take, and will tell to you;
John 16:16 a little while, and ye do not behold me, and again a little while, and ye shall see me, because I go away unto the Father.'
John 16:17 Therefore said <FI>some<Fi> of his disciples one to another, `What is this that he saith to us, A little while, and ye do not behold me, and again a little while, and ye shall see me, and, Because I go away unto the Father?'
The verse centers on "all things", "father", "hath", "mine", "said", "take", and "tell". It is saying that the verse draws attention to "all things" and "father", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "He will glorify me because of mine..." into verse 16's "a little while and ye do not...", so "all things" and "father" 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 "father" with trust shaped by these words, not by a vague optimism outside the passage.
