Nothing wrong with that - it makes good business sense. Sometimes the line between legitimate maximisation of profit and being dishonest is blurry. Proverbs 11 gives three reasons that financial honesty is a wise thing and dishonesty is foolish. Number one, because dishonesty destroys us. Number two, because it destroys relationships with others, and number three, because God hates it.
Dishonesty destroys the person practising it.
The dishonest person, says Proverbs, will be caught in the web of his own deceipt. But most seriously, dishonest dealings will be judged by God. So, wealth is not worth the cost of our own honesty, our reputation and relationships, and our standing with God. Let me now mention the second aspect of the worth of worldly wealth in Proverbs 11. And again, we see the same three reasons given.
