From: Luke 16:1-8
The Unjust Steward
 He (Jesus) also said to the disciples, "There was a rich man who had a steward, and charges were brought to him that this man was wasting his goods.  And he called him and said to him, 'What is this that I hear from you? Turn in the account of your stewardship, for you can no longer be steward.'  And the steward said to himself, 'What shall I do, since my master is taking the stewardship away from me? I am not strong enough to dig, and I am ashamed to beg.  I have decided what to do, so that people may receive me into their houses when I am put out of the stewardship.'  So, summoning his master's debtors one by one, he said to the first, 'How much do you owe my master?'  He said, 'A hundred measures of oil.' And he said to him, 'Take your bill, and sit down quickly and write fifty.'  Then he said to another, 'And how much do you owe?' He said, 'A hundred measures of wheat.' He said to him, 'Take your bill, and write eighty.'  The master commended the dishonest steward for his prudence; for the sons of this world are wiser in their own generation that the sons of light.
1-8. The unfaithful steward manages to avoid falling on hard times. Of course, our Lord presumes that we realize the immorality of the man's behavior. What he emphasizes and praises, however, is his shrewdness and effort: he tries to derive maximum material advantages from his former position as steward. In saving our soul and spreading the Kingdom of God, our Lord wants us to apply at least the same ingenuity and effort as people put into their worldly affairs or their attempts to attain some human ideal. The fact that we can count on God's grace does not in any way exempt us from the need to employ all available legitimate human resources even if that means strenuous effort and heroic sacrifice.
"What zeal people put into their earthly affairs: dreaming of honors, striving for riches, bent on sensuality. Men and women, rich and poor, old and middle-aged and young and even children: all of them the same. When you and I put the same zeal into the affairs of our souls, we will have a living and operative faith: and there will be no obstacle that we cannot overcome in our apostolic undertakings" ([St] J. Escriva, "The Way", 317).
