Lucas 18

Lucas 18:1

He prays for those who pray and appeals with those who appeal. He does not, however, pray for servants who do not pray continuously through him. He will not be the Advocate with God for his own if they are not obedient to his instructions that they always should pray and not lose heart. It says, "And he told them a parable to the effect that they should always pray and not lose heart. In a certain city there was a judge, etc." … Who would hesitate a moment to be persuaded to pray if he believes that the mouth of Jesus cannot lie, when he says, "Ask, and it will be given you … for everyone who asks, receives"? — ON PRAYER 10.2
