Some of the things I noticed while reading the text right through:

• The writer creates a sense of urgency; The Marcan Jesus is constantly on the move: he doesn’t just “hang out”. We hear words like “immediately”, “as soon as the left”, “straightaway”.
• The writer gives us little transitional summaries (1:14-15, 3:7-12, 6:53-56) and a typical day (1:21-45) that sketch out the success of Jesus preaching.
• There are three passion predictions in the centre of the story and they seem to be quite carefully structured. We will need to look at this closely when we get to it.
• The passion narrative (chapters 14-15) is a connected story in its own right.
• We will often sense there is a “sandwiching” of material (“intercalation”) going on so that two incidents take place at the same time and interpret one another. A good example is Peter’s denial being sandwiched into Jesus trial.
• The story ends very abruptly at 16:8b
