Money Mindset
The Bible seems to say two things about money. That it's all good or it's all bad. Of course, what it really says is that money, like all good things, can be worshiped as an idol. Samson worships a woman as an idol (he tells her how to released him from his vow to God), Israel worships the Torah as an idol (see the New Testament), and Adam and Eve treat food as an idol, trusting it for wisdom rather than God. Yet none of these is bad. I suspect that Christians are more suspicious of money because theologians, who are notoriously bad at being creative, industrious, and good with people (all skills that help one make money), then to teach that money (which they cannot make easily) is almost entirely bad, rather than hitting the balance appropriately.
