I recall my discussion with a particular Christian from an earlier thread where I was arguing for the ability of God to create a world where there is no suffering and his objection was that we can't conceive of what it would be like to create an entire world without suffering. At the time I conceded that we could only assert that there are no logical contradictions, but now I've had another thought that I wasn't concentrating on before.
Today I was toying around with some of the simulators in the physics department -- tweaking constants, watching simulated stars explode and birth new stars, changing the laws of physics absurdly for fun -- when I realized something important that I've always sort of known but didn't place enough emphasis on.
If we can program it, God can do it.
This has to be true. Why couldn't God the Almighty actualize something that we mere mortals can program ourselves? This is actually just a neat way to conceive of what is meant by "possible worlds" and "logical possibility." We obviously can't program a Euclidean square-circle (an ontological possibility), but for example we can program any kinds of laws of physics that we want since the laws of physics are contingent -- and so could God.
In fact, we have programs that already exist in which the characters (were they alive) don't suffer. Not only that, but many games have a "god mode" that can be entered in which the characters don't take damage or suffer pain.
If we can program it, God can do it! There's nothing inconceivable about it -- any possible objection that can be raised is met by simply adding more lines of code, and God has an infinite program size to work with.
Thus the objection, "God creating a world without suffering isn't something we can conceive" or "There could be some inexplicable problem with doing that" fades away.
