  2. Exposition

Why does the author say that John was not the light?

John 1:8 (ESV)

8 He was not the light, but came to bear witness about the light.

It appears as though there were some groups who elevated John above Jesus (e.g., Acts 18:25; Acts 19:1–7). It may be that the writer of the Gospel seeks to correct this kind of thinking, which is why he emphasizes that John only came to be a witness to the light. Alternatively, he could simply be comparing John to Jesus.1
