16–18 “When you practice some appetite-denying discipline to better concentrate on God, don’t make a production out of it. It might turn you into a small-time celebrity but it won’t make you a saint. If you ‘go into training’ inwardly, act normal outwardly. Shampoo and comb your hair, brush your teeth, wash your face. God doesn’t require attention-getting devices. He won’t overlook what you are doing; he’ll reward you well.
19–21 “Don’t hoard treasure down here where it gets eaten by moths and corroded by rust or—worse!—stolen by burglars. Stockpile treasure in heaven, where it’s safe from moth and rust and burglars. It’s obvious, isn’t it? The place where your treasure is, is the place you will most want to be, and end up being.
