Luke 18:1-8

1 He also spoke a parable to them that they must always pray, and not give up,  2 saying, “There was a judge in a certain city who didn't fear God, and didn't respect man.  3 A widow was in that city, and she often came to him, saying, 'Defend me from my adversary!'  4 He wouldn't for a while, but afterward he said to himself, 'Though I neither fear God, nor respect man,  5 yet because this widow bothers me, I will defend her, or else she will wear me out by her continual coming.'”

6 The Lord said, “Listen to what the unrighteous judge says.  7 Won't God avenge his chosen ones, who are crying out to him day and night, and yet he exercises patience with them?  8 I tell you that he will avenge them quickly. Nevertheless, when the Son of Man comes, will he find faith on the earth?”
