Christ's Economics

Piper summarizes well the need for a Biblical economics in an affluent culture

God does not prosper a business so that a man can move from a Buick to a BMW. God prospers a business so that hundreds of unreached peoples can be reached with the gospel...

Too many are more shaped by the consumer culture than by the economics of Christ. They still operate on the simple rule: If you earned it, you deserve it. It's yours; use it for your own material comfort. They have been taken in by the half-truth that says we glorify God with money by enjoying thankfully all luxuries He enables us to buy. The true half is this: we should give thanks for every good thing God gives us. That does glorify Him. The false half is the subtle implication that God can be glorified in this way by every decent purchase we make.
