Considering the Parable of the Dishonest Manager (Luke 16:1-13), what is the primary lesson Jesus is trying to convey about worldly wealth and eternal values?

A That dishonesty is acceptable if it leads to personal gain. B That Christians should strive to accumulate as much wealth as possible. C That we should use worldly wealth wisely to gain eternal rewards and demonstrate faithfulness, as worldly wealth is fleeting. D That it is impossible for a rich person to enter the kingdom of heaven.
