Did our God make a scarce world?

Rob Bell recently did an interview with Christianity Today and had some great insight into the depth of tithing:

“When I prepare to teach a text there are a few questions I always ask. First, “What’s the thing behind the thing?” and “What’s the truth behind the truth?” So if we’re talking about tithing, we’re really talking about generosity and participation. And if we’re talking about generosity and participation, then we’re really talking about whether you view the world as a scarcity or as a world governed by a Trinitarian God. Is the universe at its core a sliced-up pie where you grab your slice and then protect and defend it? Or do you believe that at the core there is an endlessly self-giving, loving community of God we are invited to step into?

So you can talk about tithing—giving your 10 percent. Or you can wrestle with a scarcity versus a Trinitarian view of the universe with tithing perhaps being an implication at the end of the message.”

There is so much depth to this truth. Why do we treat our world as if God made it a scarce commodity or that He is holding back from us?
