Perhaps this is our Lord's own comment on the parable. Always to pray] On the other hand, the rabbis taught that God must not be fatigued by too frequent prayer. Three times a day was enough. 'If a man comes to address you every hour, you say that he holds you cheap: the same is true of God, whom no man ought to fatigue by praying every hour.' The words are to be taken literally, because even purely secular acts, when done to God's glory, are acts of devotion. The whole lives of the faithful should be, in Origen's words, 'one great connected prayer.' Faint] i.e. become weary.
