This is from Galileo Unchained, an interesting and amusing site for atheists. We like this piece so much that we are taking the liberty of quoting it in full:

In the beginning … God walked in the Garden of Eden like an ordinary supernatural Joe.  He dropped by Abraham’s for a cup of coffee and a chat.  He didn’t know what was up in Sodom and Gomorrah and had to send out angelic scouts for reconnaissance: “The outcry against Sodom and Gomorrah is so great and their sin so grievous that I will go down and see if what they have done is as bad as the outcry that has reached me” (Gen. 18:20–21).

But, like Stalin gradually collecting titles, God has now become omniscient and omnipotent.  He’s gone from needing six days to shape a world from Play-Doh and sprinkle tiny stars in the dome of heaven to creating 100 billion galaxies, each with 100 billion stars.

That’s 6,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 kg of universe.

And yet, oddly, his biblical demonstrations of power faded with time.  From creating the universe, he’s weakened such that appearing in a grilled cheese sandwich is about as much as he can pull off today.  He has the fiery reputation of the Wizard of Oz but is now just the man behind the curtain.

Even God’s punishments became wimpier.  A global flood, with millions dead is pretty badass.  Personally smiting Sodom and Gomorrah is impressive, though that’s a big step down in magnitude.

And it’s downhill from there — God simply orders the destruction of Canaanite cities, and to punish Israel and Judah, he allows Assyria and then Babylon to invade.  As Jesus, he doesn’t kick much more butt than cursing a fig tree, and today he simply stands by to let bad things happen.

Maybe God’s power diminishes as the universe’s dark energy increases?
