"I mean, you read the Bible so you must know that Christ did not fulfil OT prophecy. Have you ever wondered why?"

That suggests like many christians in another ways, that swallowed the turkey.

The OT prophesies, the physical etc, set the stage for the now spiritual.
Jesus would have been ruling as King when he sat at the RHS of God.

"Revelation also prophecies Muhammad," -> I'd have to SEE that said line up ?

Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God; and those who hear will live.
(Spiritually dead?).

I'll happily take that very little as you put it
