In the Parable of the Unjust Steward (Luke 16:1-13), what is the central lesson Jesus intends to convey regarding the use of 'worldly wealth'?

A That Christians should actively engage in dishonest practices to secure their future. B That material wealth is inherently evil and should be avoided at all costs. C That believers should use their resources wisely and generously to gain eternal rewards. D That accumulating wealth is a sign of God's favor and should be pursued diligently.
