In matter-ism (materialism), there can be nothing wrong with the world since there is no right way for the world to be in the first place. Everything is just matter in motion and that's that. In Mind-ism (monism) there's a different route to the same problem. There cannot be a problem of evil, even in principle, since in Mind-ism even morality is maya; illusion. In neither story, then (if we're to be consistent with their principles), can the issue of evil be raised. But in real life the problem comes up all the time. That's the difficulty.

Man had freedom to choose the good, but this same freedom also allowed him to choose the bad. This is called moral freedom.

Our souls - our invisible selves - bear the mark of God Himself. We're like God in that we bear His image.

I want people to see that Christianity claims to be true in the deep sense, and if it isn't, then it solves nothing at all.

If man is not special, if he's not deeply different from any other thing, then there's no good reason not to treat him just like any other thing when it's convenient for us to do so.

Our innate, built-in human value is the reason we have binding duties or obligations towards each other that we don't have towards any other kind of thing. It's also the reason we have unalienable human rights. If man's God-given, special value falls, then unalienable human rights fall, too.

Something good made something bad possible (though not inevitable). Humans, however, didn't use their freedom well. Instead of using it to honor God in friendship, they used it to rebel.
