As soon as Jesus chooses his disciples, he looks to them and gives them this speech. In it, he’s preparing them for what’s ahead, and all the persecution and temptations they would face. To prepare them, he shows them what it looks like for their world to be turned on its head. He turns their ideas of blessing upside-down, and he turns their ideas of justice upside-down. But Jesus knows that we don’t naturally live like this; he knows that we need to be taught. And so he says that he’s the only teacher who can teach us to live like this, and rest the foundation of our lives on.
