To cast out demons is just another way of saying that those who suffer from physical and/or mental illnesses would be healed.
I can also claim that your post is just another way of saying "I don't want to know that there are malicious supernatural forces", but that would probably be truer.
No.These illnesses are called demons or evil spirits.
How does a "disease" talk? It can't. Demons do.
Explain demons controlling people?? When i get a cold i don't go robbing banks!
Dieases don't "leave" people either. mabye you can make someone sweat, or filter blood. But in both cases, the disease is extracted, it doesn't "leave". LEaving implies a degree of intent. Diseases and conditions do NOT have intents. Demons do.
1 Corinthians 10:20
No, but I say that the things which the Gentiles sacrifice, they sacrifice to demons and not to God; and I do not want you to become sharers in demons.
Do you actually think that people at any time, sacrificed to diseases?? LOL! ridiculous!
This verse has got to be one of the BEST bulwarks against your odd redefinition of "demon".
