“Jews are obligated to fulfill the particularities of Mosaic law. They don't light Sabbath candles simply because candles make them feel close to God, but because God commanded the lighting of candles: Closeness might be a nice by-product, but it is not the point. Christians will understand candle-lighting a little differently. Spiritual practices don't justify us. They don't save us. Rather, they refine our Christianity; they make the inheritance Christ gives us on the Cross more fully our own... Practicing the spiritual disciplines does not make us Christians. Instead, the practicing teaches us what it means to live as Christians.”
