This parable is what the rabbis called “from the lesser to the greater.” If it is the case that even this cynical judge caved in to constant appeal, how much more will God eventually respond to those who, like the widow, keep pleading for what they desire. (Of course, what you are praying has to be in God’s will for you.) Paul persevered longer and suffered more than most any other early disciple of Jesus Christ. He described what he himself had learned the hard way:
“And not only that, but we also boast in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not disappoint us, because God’s love has been poured into our hearts through the Holy Spirit that has been given to us (Romans 3:3-5 NRSV).”
By your perseverance, you are showing God not only what you seek, but also who you really are. And only you can persevere. God will not do it for you. But if you choose to persevere, God will secretly reward you with the power to continue doing so.
