Then he told them a parable about the necessity for them to pray always without becoming weary. He said, "There was a judge in a certain town who neither feared God nor respected any human being. And a widow in that town used to come to him and say, 'Render a just decision for me against my adversary.' For a long time the judge was unwilling, but eventually he thought, 'While it is true that I neither fear God nor respect any human being, because this widow keeps bothering me I shall deliver a just decision for her lest she finally come and strike me.'" The Lord said, "Pay attention to what the dishonest judge says. Will not God then secure the rights of his chosen ones who call out to him day and night? Will he be slow to answer them? I tell you, he will see to it that justice is done for them speedily. But when the Son of Man comes, will he find faith on earth?" (Lk 18:1-8)
The author of this passage tells us that he is telling a parable and the parable has a purpose. The parable wants to communicate about prayer and the necessity of prayer and prayer without ceasing. Usually a parable make the hearer to decide about the message (parable of the Good Samaritan where the listener is asked to reply as to who was really a neighbour)
The judge was a wicked man. He never bothered about justice. He was not bothered about God and he did not even bother about human. For him nothing was a matter of concern. He lived his life and that was everything. Others were not his concern. He did not want to be disturbed by others. If at all he did some good it was because he wanted to avoid disturbance and irritation.
Even wicked people do some good because of selfish motives. Selfish people also do good. Jesus argument was that even selfish people do good and hence much more good would be done by God who is selfless and totally good. If good can come out of evil then naturally good will come in abundance form good God.
