Charles Spurgeon Commentary Luke 18:1-7

"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?" — Luke 18:1-7 (ASV)

And he spake a parable unto them to this end, that men ought always to pray, and not to faint; saying, There was in a city a judge, which feared not God, neither regarded man: and there was a widow in that city; and she came 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 by her continual coming she weary me. And the Lord said, Hear what the unjust judge saith. And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?

He hears their prayer a long time because it does not weary him.

It pleases him, he loves to hear their sighs and cries, but will he not yield to their entreaties? What think you? Shall not the good, gracious, loving God yield at length?
