In the Parable of the Unjust Steward (Luke 16:1-13), what is the primary lesson Jesus intends to convey, despite the steward's dishonest actions?

A That dishonesty is acceptable if it benefits oneself in the short term. B That believers should always prioritize material wealth over spiritual values. C That shrewdness and foresight should be used to prepare for the future, particularly in light of eternity, even if it requires unconventional methods. D That God approves of manipulating others for personal gain.
