Luke 18:1-8

1 And he spake a parable unto them to the end that they ought always to pray, and not to faint;

2 saying, There was in a city a judge, who feared not God, and regarded not man:

3 and there was a widow in that city; and she came oft unto him, saying, Avenge me of mine adversary.

4 And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man;

5 yet because this widow troubleth me, I will avenge her, lest she wear me out by her continual coming.

6 And the Lord said, Hear what the unrighteous judge saith.

7 And shall not God avenge his elect, that cry to him day and night, and [yet] he is longsuffering over them?

8 I say unto you, that he will avenge them speedily. Nevertheless, when the Son of man cometh, shall he find faith on the earth?
