The parable of the talents tells us we should use to the utmost whatever talents the Lord has given to us. This is entrepreneurship. Entrepreneurs find better and better ways to produce and to serve. Just as the priesthood is a faithful Christian ministry, so too is every useful occupation. Business management is the ministry of prosperity and such ministry flourishes within the free market system.
Gospel principles teach honesty, faithfulness, peace, patience and service to others.

Clients and customers prefer to go to persons with high ethical principles whom they can trust. Greed is trying to take from others.
