Then He spoke a parable to them, that men always ought to pray and not lose heart, saying: “There was in a certain city a judge who did not fear God nor regard man. Now there was a widow in that city; and she came to him, saying, ‘Get justice for me from my adversary.’ And he would not for a while; but afterward he said within himself, ‘Though I do not fear God nor regard man, yet because this widow troubles me I will avenge her, lest by her continual coming she weary me.’” Then the Lord said, “Hear what the unjust judge said. And shall God not avenge His own elect who cry out day and night to Him, though He bears long with them? I tell you that He will avenge them speedily. Nevertheless, when the Son of Man comes, will He really find faith on the earth?”
Believers should always continue in prayer, no matter how dire a situation may look. God honors persistence. He is the Lord of miracles and mercy and will move upon our requests as we continue to petition Him. God is love; He cares about you, your situation, and heart.
There is a caveat to this promise, however: we must pray in the confines of His will (1 John 5:14).
Will He really find faith on the earth?
This is a very interesting question posed. Basically, it's asking, Who will truly believe Jesus' words and by faith act like the widow through persistent prayer, waiting, and believing for the goodness of God.
Jesus will act on behalf of His elect in much greater truth and love than the unjust judge. Will you take what is on your heart and bring it to the Lord continually until he avenges you? Whether you seek freedom from a sexual addiction, are a wife of a sex addict, or need something else… take this promise to heart.
