Luke 18:1-9

And he spake a parable unto them to the end that they ought always to pray, and not to faint; saying, There was in a city a judge, who feared not God, and regarded not man: and there was a widow in that city; and she came oft unto him, saying, Avenge me of mine adversary. And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man; yet because this widow troubleth me, I will avenge her, lest she wear me out by her continual coming. And the Lord said, Hear what the unrighteous judge saith. And shall not God avenge his elect, that cry to him day and night, and yet he is longsuffering over them? I say unto you, that he will avenge them speedily. Nevertheless, when the Son of man cometh, shall he find faith on the earth? And he spake also this parable unto certain who trusted in themselves that they were righteous, and set all others at nought
