"And he spake a parable unto them to this end, that men ought always to pray, and not to faint; Saying, There was in a city a judge, which feared not God, neither regarded man: And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary. And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man; Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me. And the Lord said, Hear what the unjust judge saith. And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?" (Luke 18:1-8 AV)
After speaking this parable, Jesus asked the question,"Nevertheless when the Son of man cometh, shall he find faith on the earth?" He implied that when he returned to the earth, he will not expect to see such great faith as this widow had. She had great faith that she could convinced this unjust judge, and the ability that this judge could help her. By persisting, she accomplished her desire.
Although mankind has been making good advancement in science and has more knowledge than ever, their faith in God is in fact decreasing. When men become more dependent on their science and technology, they draw away from God. To the extent, when Christ returns, he will be appalled by the lack of faith in him, particularly in praying.
We may think that mankind should learn from their history, and their would become wiser as the days go by. In fact, this just the opposite. When men are so content with what they have, and so busy to get more than they have, God is pushed to one side.
Isnít this true in many Christians lives? Many good stories can be told by some spiritual old warriors, but are they in the battle? In the Bible, many spiritual men fell as they grew old: Abraham took an Egyptian woman as his concubine to have a son, Moses died outside Canaan because he smote the rock out of anger, Gideon had many wives, Samuel did not discipline his rebellious children, Saul went and sought council of a witch before going to war, David numbered his people out of pride. In Revelation 3, God describes the end time church as "lukewarm". Lukewarm churches have no zeal for God and does not see their spiritual problems. Although there are 6000 years of history behind us, the general status of the Christian churches today is not commendable.
With these examples before us, and we all become older, we need to make sure that we are not in their shoes. Thus when we meet God, he would not ask, "Why are you not taking heed about by warning in the Book that I have written for you?"
