The Bible certainly warns us against the desire to be rich, and those warnings ought to be heeded (1 Timothy 6:9,10). Contentment is the hallmark of the genuine believer in Jesus who lives on limited resources. 

If, on the other hand, you are already rich, it is not the fact that you are a millionaire that in the end messes you up.  It’s the fact you trust in uncertain riches which becomes your undoing (1 Timothy 6:17) . So Paul distinguishes between the non-rich who desire to be rich (they should be content) and the rich (they should guard against the temptation to trust their wealth rather than God).

That having been said, GenX Finance has an interesting post that is worth a read: The Top Five Ways to Become a Millionaire  (HT: Hugh Hewitt).

Is there anything about what we believe that prohibits Christians of simple means from managing their money in such a way as to become wealthy? What are the benefits? What are the pitfalls?
