I like Steve Murrell's answer at the reluctant leader... (Warning: it's probably not what Joel Osteen would say).
No matter if you are rich or poor, young or old, male or female, educated or illiterate - I believe God wants you to be rich, but maybe not the kind of rich that lands you on the cover of Fortune magazine.
1. God wants you to be RICH IN GENEROSITY.
Here's how Paul described the poor Macedonian church: "Out of the most severe trial, their overflowing joy and their extreme poverty welled up in RICH GENEROSITY." (2Cor8:2)
This verse shows that even poor people can be rich in generosity.
2. God wants you to be RICH IN GOOD DEEDS.
Notice what Paul instructed Timothy to tell the wealthy people in his church. "Command them to do good, to be rich in good deeds, and to be generous and willing to share." (1Tim6:18)
No matter how much you have, you can be rich in generosity and rich in good deeds. That's why I say GOD WANTS YOU RICH!
