You have brought up a pretty interesting topic - especially with the world economy in such chaos.
One thing that God calls each of us to be is a good steward. That means that we are to take care of the things that He gives us (finances, time, health, etc) and not squander them. We are to make good investments of our time and finances so that our efforts bear good fruit for God.
The topic of Christian finances is one that I plan on doing a study on very soon.
