Some people believe Christs and God to be seperate, some people think Jesus was a metaphor and wasn't real, some people think Jesud was a metaphor but was ultimately only a man. Really there are so many different perspectives on this: its an entire field of study within the study of religion.
And would God be all knowing and know that he will be put on the cross?
And also the whole thing with Mary being a virgin and giving birth to GOD? oh helllll naw (sorry.)
Which is why I think Jesus was a messiah sent with a message but along the way his message was somehow distorted to be interpreted as him saying he is God, when he was just the one with a message from the dude upstairs
