Of course we can try, but our efforts aren't having a huge impact. It's like a trickle of goodwill against a raging torrent of selfishness and greed.
And, honestly, I'm not sure if I would prefer to be created with the ability to do good only. I know many people are appaled at the idea, likening it to mental slavery. What do you think?
My perspective is that it really doesn't matter whether I would or wouldn't prefer being made to do good. Fact is, I have a choice because thats what God decided.
