Hello. Doing ok aside from this situation? :)

So let me get this right in my own words and you tell me if im correct please.

You have met a theistic satanist and they are trying to convince you to allow yourself to be possessed by an evil spirit, and in return you will receive power.

If this is correct I have a question please.

What did they predict with stunning accuracy? Surely not just a power always wanted...

Wisdom says an evil spirit can relay your desires to another. Wisdom also says that evil spirits lie.
