He told them a parable to show that they should keep on praying and never lose heart:
'In a certain city there was a judge who had no fear of God or respect for man, and in the same city there was a widow who kept coming before him to demand justice against her opponent. For a time he refused, but in the end he said to himself, "Although I have no fear of God or respect for man, yet this widow is so great a nuisance that I will give her justice before she wears me out with her persistence." ' The Lord said, 'You hear what the unjust judge says. Then will God not give justice to his chosen, to whom he listens patiently while they cry out to him day and night? I tell you, he will give them justice soon enough.
--Luke 18: 1-5 (REB)
