How do I explain so people that the devil is…

How do I explain so people that the devil is not behind all viruses, sickness and natural disasters?
And that although hard to understand at times God uses these things for good?

Whenever I try to defend Gods sovereignty related to this I get people saying “How could you! God is good and loving! He saves us! This is all the devils work! Stop spreading lies!”

Am I wrong to say God allows directly and indirectly all these things to occur and does so for direct or indirect purpose? And especially when it comes to natural phenomenon where an angle (like the devil) has little to no authority? And if we take Job into account only authority given to him by God?

Just want to know you’re opinions and advice on this.. thank you and Godbless.
