Luke 18:1-8 Jesus told his disciples a parable about the need to pray continually and never lose heart:
'There was a judge in a certain town,' he said, 'who had neither fear of God nor respect for man. In the same town there was a widow who kept on coming to him and saying. "I want justice from you against my enemy!"
'For a long time he refused, but at last he said to himself: "Maybe I have neither fear of God nor respect for man, but since she keeps pestering me I must give this widow her just rights, or she will persist in corning and worry me to death".'
