Luke 18:1-8

He told them a parable to illustrate that it is necessary always to pray and not lose heart. He said: “In a city there was a judge who did not fear God or regard man. And a widow was in that city. She came to him, saying, ‘Avenge me against my adversary.’ “He would not for a while. Yet afterward he said to himself, ‘Though I do not fear God or respect man, yet because this widow troubles me, I will avenge her, lest by her continual coming she will weary me.’ ” And the Lord said, “Hear what the unjust judge says. And shall not God avenge His own elect and be patient with them, who cry day and night to Him? I tell you, He will avenge them speedily. Nevertheless, when the Son of Man comes, will He find faith on the earth?”
