I agree. I just happen to believe that each of us has an ultimate standard given to us by God at our creation and you don’t. It is this standard that I base my beliefs on.
Has the specific prophecy which you use for proof been fulfilled yet? If so, is there proof of this fulfillment?
Do you understand if there are more than one ultimate standard and they differ that one or more of them are wrong? And that if those standards differ they can not be the objective ultimate standard?
To deny the logic of this is to deny logic itself in favor of some gobbledegook philosophy.
Yes, specific prophecies have been fulfilled.
There are over 300 specific Old Testament prophecies fulfilled in the life, death, and resurrection of Jesus Christ.
Again, the time that these prophecies were written is known.
The fulfillment of the prophecies was recorded by eyewitnesses in the time of other eyewitnesses who would have refuted them if they didn’t happen.
