Earlier this week, a friend of mine, who more or less espouses this view, alerted me to this ad campaign.
The thought of it does weird things to my stomach. It kind of awakens my inner reactionary and makes me want to stamp up and down on a poster while wearing stilettos and rant or something. This would probably not go very well, partly because I never wear heels and a first attempt at stilettos while trying to destroy something would likely end up destroying me more quickly than the poster. Also I don't think reactionary reactions are usually very effective.
Having said that, I've got to say I agree with Wildmon on this one. I just don't see where the basis of goodness comes from without a God. We have sort of discussed this here before. Doing unto others as you would have them do unto you, while coming from the mouth of Jesus, might work as a basic manifesto for all people with or without a belief in God. But I've discovered that, just because I love to be given books for my birthday, not everybody does, so if I literally did unto others as I would have them do unto me, some people might not consider I had given them a good birthday present. On a larger scale, somebody might say that assisted suicide is good because it prevents suffering, and I might say it's bad because it short-circuits personal development and denies God's sovereignty over that life.
Although I think there are really solid reasons for believing in the Christian God, for the sake of argument let's say I could be wrong. Or the assisted-suicide-advocate could be wrong. Or somebody that believes in a totally different kind of God could be wrong. But we can't all be right about what good is. And without a God, who decides? I suspect even atheists have different ideas about what constitutes "good" in any given scenario. So do Christians, if it comes to that. But atheists, as far as I can tell, don't have any external basis for deciding what goodness is; it's entirely arbitrary. Christians may not always get our goodness right, but at least we have a basis for it. I think, frankly, that an atheist's basis is the same one--it's just not acknowledged.
On the other hand, I do think there's a reason to "be good for goodness' sake," particularly for Christians. We have a God who loves, who didn't want robots, who doesn't add up points for us to get into His good graces. He wants to relate to us, and He wants our goodness to come out of relating to His goodness--He is goodness. I'd rather be good for His sake than because Santa Claus was coming to town . . .
