Comments and Commentaries:
Earlier John asserts that Jesus (The Word) created all things. This verse adds the idea that he sustains everything that he made because he was “life” and it’s life that is sustained by God’s word.
Hebrews 1:3 supports this idea it says, “who is the radiance of his glory and the representation of his essence, sustaining all things by the word of power…”
That life is “in him” means “he is the source of this life.”
It seems that “life” is referring to eternal life, not physical life. According to most of the commentators the Greek word for life is only used in John to refer to eternal life.
In John it seems that eternal life is not longevity as much as it is quality. He talks about “real” life or “true” life in contrast to just life. We should think of not only never ending life but the best quality of life also. John’s “life” is not mere existence.
That life gave “light” to mankind or the human race. Whereas the first phrase refers to everything; plants, plants, animals etc., the last phrase refers to the uniqueness of humanity being created in the image of God with such a nature to be able to recognize how the universe declares the glory of God. Mankind also has been presented with the light of life of God’s son. God’s very own Jewish people will not comprehend it but many will.
CLV (Chuck Larsen Version): The Word had eternal life in himself and he brought that life to mankind so that all might comprehend the truth.
