Jesus knew it would be difficult for His followers to continue to pray especially during hard and trying times and so he told them this story of a widow protesting an unjust judge and how she was able to change his mind and how boldly then we ought to protest God to act on our behalf against all forms of oppression. When the "Justice of Jesus" is enacted it comes in a very different way than any human government, judge, or people group can ever bring. The Justice of Jesus is always perfect and full of mercy and this Just Judge and King we must protest if we want to become "overcomers" in an unjust world.
