In the Parable of the Unjust Steward (Luke 16:1-13), what theological principle is Jesus primarily illustrating through the steward's dishonest yet shrewd actions?

A That dishonesty can be justified if it leads to a positive outcome for oneself and others. B That worldly wealth, even if acquired unjustly, can be used to secure eternal benefits. C That believers should be as diligent and resourceful in pursuing spiritual goals as worldly people are in pursuing material gain. D That forgiveness is always granted to those who repent, regardless of the severity of their past actions.
