Re-reading Mark 14 is interesting. In Gethsemane, the disciples were urged to stay awake, watch and pray so that they might not fall into temptation. Jesus himself stayed awake and prayed – presumably including prayer to remain faithful under the forthcoming trial.
A sobering statement on human nature. The disciples could see Jesus, the Son of God incarnate, praying to his father that he might not yield to temptation. Yet they thought (implicitly or explicitly, it doesn’t matter) that they could endure without the Father’s help. Astounding – and sobering.
That also gives a point of contact between chapters 13 and 14. The concluding exhortation in chapter 13 is “stay awake”, the same thing Jesus has to tell the disciples in chapter 14. Could this be one key to working out Mark’s intent in these chapters?
