Those of us “slaves” who are still alert when the master comes get a special reward contained in the surprising thing the returning master does. Here is how Jesus put it. “Blessed are those slaves whom the master finds alert when he comes; truly I tell you, he will fasten his belt and have them sit down to eat, and he will come and serve them.” Jesus serves us. He nurtures us. He puts on his apron and gives us food. You don’t suppose that food is his body and his blood and maybe more? They are on their way to Jerusalem as he says these things! Could all of this be part of the Father’s good pleasure?
Then, blessed are those who persist in waiting - but the waiting is not about being good for a long time, it’s about patiently waiting. After all, “if the owner of the house had known at what hour the thief was coming, he would not have let his house be broken into.” Suddenly Jesus’ image makes Jesus into a burglar coming at night and, with this shift, he subverts any attempt to make following him into being better than one’s neighbour. It’s not about being good, it’s about following Jesus.
