I had an idea of selling my soul to the devil to find the cure of cancer . Is selling your soul real?

Purely fiction. The soul is an integral part of your personality. You can't sell just the soul.

You'd have to sell your whole being...body, mind, and soul. And by the way all souls already belong to YHWH. He has predestined some for life, and some for death.

That's all.

I believe that some people do make a pact with satan. This pact is called .. selling one's soul to satan. Bad.

Whereas christians don't make a pact with God. Instead God makes a COVENANT with humankind. Good.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
