And why there is so much evil appearing in the modern world and how to counteract it effectively
The best explanation I've heard of good and evil I heard on a YouTube video several years ago.
Since pure good is timeless, it cannot exist in time. It has to exist outside of time, it was suggested in another dimension. Which makes sense to me. Therefore it's powers are limited here in "time". I think pure goods biggest impact and limitations are played out through evolution.
Because pure goods powers are limited by evolution, evil exists, until we evolve beyond it. As human beings evolve, we become more and more like the source or pure good.
I'm not trying to change any minds by this. I just want to voice my view.
I do agree with the video (above) that says evil can't be destroyed, it needs to be changed through education. I'm paraphrasing here but I think that was the basic idea.
