Jesus is the person speaking in the passage above. He talks about a time just before He returns to earth, that the kind of faith and prayer that prevails will be a rare thing. The context of His words is from the Parable of the Persistent Widow, found in the Gospel of Luke, chapter 18. The widow prevailed in her quest for justice from an unjust judge, by not giving up in her asking. Jesus uses the story to say that if an unjust judge gives in to a persistent widow, then how much more will the Holy God, who watches over all the affairs of men, grant the prayers of a prevailing woman of prayer!
It is my opinion that we are living in the time in which the Lord’s return is near, although how near, I would not like to predict. Many have made such claims in the past and have been proven to be wrong, to their embarrassment. However, there are some signs of the times which are obvious to any wise seeker of truth. The question is raised; “Will the Son of Man find faith on the earth?” We are living in a day when faith in Christ is under attack. In fact, people of faith in our Western culture are now being accused of being “politically incorrect.” Spirituality in our western worldview does not fit neatly, unless it is seen in an abstract way, or as a way of “self enlightenment or self improvement.” We are so consumed with our jobs and making a living, having so little time for anything else that we often do not have time for the really important things in life. We do not take the time to pray persistently as the widow did. The vast majority of the Church gets weary and gives up before God can reward their faith and prayer with the answer.
When Edmund Gravely died at the controls of his small plane while on the way to Statesboro, Georgia, from the Rocky Mount-Wilson Airport in North Carolina, his wife, Janice, kept the plane aloft for two hours. As the plane crossed the South Carolina/North Carolina border, she radioed for help: “Help, help, won’t someone help me? My pilot is unconscious.” Authorities who picked up her distress signal were not able to reach her by radio during the flight because she kept changing channels. Eventually, Mrs Gravely made a rough landing and had to crawl for forty five minutes to a farm house for help. How often God’s people cry out to him for help but switch channels before His message comes through! They turn to other sources for help, looking for human guidance. When you cry out to God for His intervention, don’t switch channels! Await His answer and keep looking to Him.
