Read Luke 18:1-8:
"And he told them a parable to the effect that they ought always to pray and not lose heart. He said, “In a certain city there was a judge who neither feared God nor respected man. And there was a widow in that city who kept coming to him and saying, ‘Give me justice against my adversary.’ For a while he refused, but afterward he said to himself, ‘Though I neither fear God nor respect man, yet because this widow keeps bothering me, I will give her justice, so that she will not beat me down by her continual coming.’ ” And the Lord said, “Hear what the unrighteous judge says. And will not God give justice to his elect, who cry to him day and night? Will he delay long over them? I tell you, he will give justice to them speedily. Nevertheless, when the Son of Man comes, will he find faith on earth?”
On a scale of 1 to 10, how much persistence (in comparison to the widow mentioned above) are you bringing to bear in your daily battle for the Kingdom?
