Happy if you do it

Jesus has just washed his disciples' feet, the work of a slave. Then he says that a slave does not rank above his master, and a messenger does not rank above the one who sent him. If the master doesn't think this work beneath him, his disciples needn't either.

Knowing alone isn't enough. But listen to the tone. Jesus doesn't say: you must. He says: happy are you if you do them. Doing isn't an extra burden on top of knowing. That is where the happiness lies.
