In your essay on the Nephilim, you allude to their ability to foresee the future, and say their powers derived from Satan. My understanding has always been that Satan is not able to foresee the future. Otherwise, he would have tried to prevent the crucifixion of our Lord.
I said according to tradition Nephilim had ways of knowing and predicting the future, and that this power was derived from Satan. Today, some astrologers, psychics, etc are able to manifest the same kind of power and it’s also derived from Satan. Like the Nephilim, they’re not always right but they’re right often enough that people become convinced they have supernatural ability.
