Wait, I though there was only one god? Satan is a fallen angel, but now he can mess with the cells of god's creation? Why doesn't satan give us all cancer? Especially Christians. Cancer exists because of faulty cells. Blaming satan for this shit is such a cop out. God is all powerful yet can't even get rid of satan? By the way, Jesus and Satan and their struggles are just metaphors.
Our world is in a "fallen" state. At what point is Satan to blame,
or just the fact that the world is now filled with diseases because of the natural occurrence of such things is debatable, of course. Why God allows suffering is an ongoing discussion. But every good and perfect gift comes from God. God is Love. God is Good. If we understand His true nature we can see the world for what it is and put blame where it is due. And God is all powerful but for whatever reason He is allowing us to live in this fallen state, I believe because He wants to see who will choose Him based on our own free-will. He could force us all to serve Him and submit but then how would He really know who loves Him or not?
It's not debatable. God either made diseases or he didn't. Either they evolved like everything else or god is one sick fuck. And he kinda is forcing us.
. That's not very nice of him. That's bullying and an abusive relationship. He also seems to want us to believe some pretty stupid stuff. Why give us intelligence then expect us to forgo its use?
