Is there a logical reason to disbelieve in the existence of Satan?

Yes, because it is actually Satan and his Satanists who promote the disbelief.

It protects and keeps them rich and powerful, ruling the world.

the whole world is under the rule of the devil (1 John 5:19)

The system by which Satan thrives on Earth works best when people think he doesn’t exist.

This belief is common among people who are not high in echelons of life; the ordinary people.

By worshipping and admiring the rich and powerful, these people unknowingly feed the death machine that is Satan’s rule over the world.

This famous musician knows that the ancient serpent of Genesis 3 exists because she actually serves him but her fans thought she was just being creative.

I will be giving you a testimony of a young man who worked in a hospital mortuary.

This guy was shocked when the water they used to wash corpses was so much on demand.

It was sought by rich and influential people; businessmen, politicians, religious leaders and other celebrities for Satanic rituals.

Human death is what Satan asks from people to make them rich and powerful.

He makes death such a treasure so that humans can keep killing each other.

The reason is because Satan has no life being condemned to hell (Matt 25:41)

He thrives by stealing human lives. and exchanging his destiny of hell with that of humans.

This is the reason for all death right from Abel.

So the poor, ordinary man looks up to the powerful, rich ones for sustenance.

But the majority of big ones actually look up to Lucifer who demands the blood of the common people.

So ultimately, the poor look up to their own death for sustenance.

All this has to be kept secret and that is why people don’t believe in Satan’s existence.
