The value of prayer lies not in mere quantity but in its quality. This is shown by the contrast of the two men who went up into the temple (cf. Luke 18:10), and by the injunction: ‘When you pray, do not use vain repetitions’ (Matt. 6:7). As sight is superior to all the other senses, so prayer is more divine than all the other virtues.”
