Faithfulness in money is a test of deeper trustworthiness.

Luke 16:10–12

¹⁰He that is faithful in that which is least is faithful also in much: and he that is unjust in the least is unjust also in much.

¹¹If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true riches?

¹²And if ye have not been faithful in that which is another man’s, who shall give you that which is your own?
