In the Parable of the Persistent Widow (Luke 18:1-8), what aspect of God's character is Jesus primarily emphasizing through the contrast between the unjust judge and God?

A God will eventually tire of our requests and grant them to make us stop bothering Him. B God, unlike the unjust judge, is inherently just and compassionate, and will answer the prayers of His people, especially those who are marginalized and oppressed. The parable highlights the importance of persevering in prayer, trusting in God's timing and justice. C God only helps those who help themselves. D God is indifferent to the suffering of the poor and powerless.
