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.
[God] wants you to go home, look at your bucket of seed, and determine in your heart how much you'd like to sow. He wants you to consider thoughtfully your current circumstances, your life, your potential, and your finances. He wants you to involve your family. He wants you to pray about it. And then He wants you to come up with a plan.
