"YOU HAVEN'T GOT IT RIGHT!" says the exasperated piano teacher. Junior is holding his hands the way he's been told. His fingering is unexceptionable. He has memorized the piece perfectly. He has hit all the proper notes with deadly accuracy. But his heart's not in it, only his fingers. What he's playing is a sort of music, but nothing that will start voices singing or feet tapping. He has succeeded in boring everybody to death, including himself.
Jesus said to his disciples, "Unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven" (Matthew 5:20). The scribes and Pharisees were playing it by the book. They didn't slip up on a single do or don't. But they were getting it all wrong.
Righteousness is getting it all right. If you play it the way it's supposed to be played, there shouldn't be a still foot in the house.
