When reading the Gospels, think of four different news providers.
Matthew, Mark and Luke are like daily newspapers, they tell mostly the same stories with a play by play account of what happened, from slightly different perspectives.
But John, which seems to be very different in content from the other gospels, is more like the end of the week review in Macleans magazine.
Same background story, but more reflective on what these stories mean, more focussed on the specific teaching and meaning behind the events.
Same stories, from different perspectives and angles…
