He also spoke a parable to them that they must always pray and not give up, saying, “There was a judge in a certain city who didn’t fear God and didn’t respect man. A widow was in that city, and she often came to him, saying, ‘Defend me from my adversary!’ He wouldn’t for a while; but afterward he said to himself, ‘Though I neither fear God nor respect man, yet because this widow bothers me, I will defend her, or else she will wear me out by her continual coming.’ ”
The Lord said, “Listen to what the unrighteous judge says. Won’t God avenge his chosen ones who are crying out to him day and night, and yet he exercises patience with them? I tell you that he will avenge them quickly. Nevertheless, when the Son of Man comes, will he find faith on the earth?”
This is what a parable looks like: no names, and shocking. God is blasphemously compared to an unjust judge. The parable implies that He can be worn out, get tired; nonsensical for a perfect being.
As usual, the story is actually saying the opposite of what it seems to say on superficial reading. It is all in the last line.
It seems to say God will answer prayer. It is really explaining why God does not answer prayer.
Unlike the unjust judge, God does not disdain mankind and want to be rid of us. Instead, he loves us. The parable illustrates that, if he easily gives us what we want, we will probably go away and forget about him. The last thing he wants us to do is go away and forget about him.
So he will present us with problems and fail to give us what we ask, for the sake of deepening the relationship. To progress, we must learn to be grateful, and to continue the conversation, even when he fulfills our wishes.
