Some take pains to be biblical, but many [Christian financial teachers, writers, investment counselors, and seminar leaders] simply parrot their secular colleagues. Other than beginning and ending with prayer, mentioning Christ, and sprinkling in some Bible verses, there's no fundamental difference. They reinforce people's materialist attitudes and lifestyles. They suggest a variety of profitable plans in which people can spend or stockpile the bulk of their resources. In short, to borrow a term from Jesus, some Christian financial experts are helping people to be the most successful 'rich fools' they can be.
Do you not know that God entrusted you with that money (all above what buys necessities for your families) to feed the hungry, to clothe the naked, to help the stranger, the widow, the fatherless; and, indeed, as far as it will go, to relieve the wants of all mankind? How can you, how dare you, defraud the Lord, by applying it to any other purpose?
Whomsoever controls the volume of money in any country is absolute master of all industry and commerce and when you realize that the entire system is very easily controlled, one way or another, by a few powerful men at the top, you will not have to be told how periods of inflation and depression originate.
