How can existence be evil? God created creation. He saw that it was Good. He is the great I Am.
Existence is not evil.
Existence, goodness, beauty, oneness and truth are convertible terms, so, yeah. It's like saying that good is bad.
You can blame Adam and Eve if you like, but they created a rift between man and God, which is why Jesus had to come. We are born with original sin. We need to seek him and be saved. Otherwise, he wouldn’t of had to come and suffer greatly and die for us.
“How can existence be evil? God created creation. He saw that it was Good. He is the great I Am.
Existence is not evil.”
Then why, until The Return, does evil win? You read The Book.
When God says “and it was good” I take that to mean that it would serve His purpose. His Purpose, as far as I can tell, seems to be to test to see who will follow Him in Faith and who will refuse. The earth is fallen. It is nothing. It is expendable.
Existence is most evil of ALL things.
