Warnings of Jesus:
Unfaithfulness and dishonesty will bring great loss

Whoever is faithful with very little will also be faithful with much, and whoever is dishonest with very little will also be dishonest with much. So if you have not been faithful with worldly wealth, who will entrust you with true riches? And if you have not been faithful with the belongings of another, who will give you belongings of your own? No servant can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and money.” Luke 16:10-13
