BDBD is Psalm 41:10-13

David prays with confidence. He believes in the Lord Jesus’ love, justice, and power. He knows that the Lord loves and is full of compassion and mercy. His trust and faith in the Lord God are completed with an answer as he desires.

Jesus gave a parable to his disciples to show that they should always pray and not give up, just as David did. He said: “In a certain town there was a judge who neither feared God nor cared about men. And there was a widow in that town who kept coming to him with the plea, ‘Grant me justice against my adversary.’

For some time he refused. But finally, he said to himself, ‘Even though I don’t fear God or care about men, yet because this widow keeps bothering me, I will see that she gets justice so that she won’t eventually wear me out with her coming!'”
And the Lord Jesus said, “Listen to what the unjust judge says. And will not God bring about justice for his chosen ones, who cry out to him day and night? Will he keep putting them off? I tell you, he will see that they get justice, and quickly. However, when the Son of Man comes, will he find faith on the earth?” (Luke 18:2-8)
