Your attempt to compare God to a psychic only exposes your inability to seriously engage in this debate.
I’m not the one comparing God to a phychic; it’s you and the open theists.
You are the one who says God cannot know the future, and you are the one who says phychics cannot know the future. (I agree with the phychic part)
You are the one who says that God only vaguely knows the future, and you are the one who just said that phychics only vaguely know the future. (I agree with the phychic part)
I believe God knows the future, and I believe God knows every detail of the future.
I elevate God from the phychics, and you equate God to the phychics.
And, according to Ezk 28:12, Satan knows the past and the present, which is another comparison open theists such as you do to God.
Do these psychics know anything more than the average human? No. They're pretenders.
Not if Satan is their source.
