A number of challenging statements are made in this chapter of Mark. 

We focus on the story of Jesus cursing a fig tree, which seems somewhat unfair given that it was not the season for figs. There's something interesting here because when the disciples ask about it Jesus answers with comments about prayer. We find a few connections, but are unable to fully resolve our questions about this passage. Helpfully there are plenty of other passages that make the important things clear - even in this part of Mark.
