Supply Side Jesus

The comic parody The Gospel of Supply Side Jesus is pretty funny (via boingboing). But I thought Jesus really was a supply-side thinker. It's right here, Matthew 13:12:

For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.

(Note: this is a joke, so please no flames from theologians. Hey, I like saying that.)
