If you’re just joining me, I’ve been responding to my Christian friends who ask, “Why would someone who doesn’t believe in God care?” I have suggested why I would care about anything at all and about right and wrong. This time, I’ll explore the reasons a non-believer has for caring about other people.
The prior posts actually apply to this question as well. First, humans are social animals, so caring for others is literally in our DNA. Second, even an unbeliever can observe that what goes around comes around.
I have only one thing to add, and once again the Bible provides a germane quotation: “It is more blessed to give than to receive” (Acts 20:35). The Message translation renders it, “You’re far happier giving than getting.” And it’s true. We feel good when we help others. We feel bad when we’re selfish.
Atheists may be without God, but they are not stupid. Even an atheist is smart enough to do what feels good.
This has been a short post, so let me jump right to the next subject: Why Do Atheists Care About Religion?

Interesting, but If there is no Creator, has there any meaning to our life?
I’m not an atheist, but I don’t believe in forcing my beliefs on others either, everyone has their own journey.
>> If there is no creator, [how is] there any meaning to our life?
I hope you’ll stick around, KL. I find myself blogging about that often: here, here and here, for example.
