Passage
all things through him did happen, and without him happened not even one thing that hath happened.
all things through him did happen, and without him happened not even one thing that hath happened.
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God;
John 1:2 this one was in the beginning with God;
John 1:3 all things through him did happen, and without him happened not even one thing that hath happened.
John 1:4 In him was life, and the life was the light of men,
John 1:5 and the light in the darkness did shine, and the darkness did not perceive it.
The verse centers on "all things", "through", "happen", "without", "happened", "even", and "hath". It is saying that the verse draws attention to "all things" and "through", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "this one was in the beginning with..." into verse 4's "In him was life and the life...", so "all things" and "through" 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 "through" with trust shaped by these words, not by a vague optimism outside the passage.
