And he spoke a parable unto them to this end, that men ought always to pray, and not to faint;
All Commentaries on Luke 18:1 Go To Luke 18
Augustine of Hippo
AD 430
[The Lord] taught us to pray to receive this blessed life. He taught us not to pray with much speaking, as if we were more likely to be heard, the more words we use in our prayer. The Lord said, “He knows what is needful for us before we ask him.” For this reason, it may seem strange, although he cautions us against much speaking, he still urges us to pray since he knows what is needful for us before we ask for it. He said, “We should always pray and not faint.” He used the example of a certain widow who wished to be avenged of her adversary and petitioned an unjust judge so often that she made him listen to her. She made him listen not through any motive of justice or compassion, but through weariness of her insistence. In this way, we were to learn how surely the merciful and just God hears us when we pray without ceasing. The widow, because of her continual petition, could not be treated with contempt even by an unjust and wicked judge.
