Here is the sermon.
I preached from my own translation of the passage, which is below along with the photo I refer to at the beginning.
18:1 He was telling them a parable to show them the need always to pray and not become discouraged. 2 He said, “there was a certain judge in a certain town who did not fear God or respect people. 3 There was a widow in that town and she was continually coming to him and saying, ‘Give me justice from my opponent.’ 4 He was not willing for a time but after a while, he said to himself, ‘Even though I don’t fear God or respect people, 5 because this widow is causing me trouble, I will give her justice so that she won’t disgrace me by continually coming.’”
6 The Lord said, “Listen to what the unjust judge says. 7 Won’t God grant justice to his chosen ones who cry out to him day and night? And he is patient with them! 8 I say to you that he will grant them justice quickly. However, when the Son of Man comes, then will he find faith on the earth?”
