Mat 20:23 You shall drink indeed of my cup, and be baptized with the baptism that I am baptized with: but to sit on my right hand, and on my left, is not mine to give, but [it shall be given to them] for whom it is prepared of my Father.

Christ's predictions can be applied to us all. In this case, Christ, in predicting the suffering of his apostles (all of who died by persecution) but he is also talking about the loss we all suffer, including the loss of our own lives. Christ was, in a very real sense, the universal man, living a life we can all related on the basis of our shared emotions and inescapable fact of human suffering. The central fact of Christ's unjust death is just a perfect foreshadowing of our own, individual deaths (and rebirths).

We all do drink of his cup and suffer taking the plunge, whether we choose to or not. How unlike someone like Mohammed, who was not only a man, but one who had privileges of power and sex that most of us do not even aspire to, much less related to. Mohammed too died, but his death was an act of vengeance (poisoning by a woman whose family Mohammed killed) so unlike most of our deaths.

One of the reason that I cannot quite buy into the complete diefication of Christ is because he makes statements like this, where he clearly separates himself, his will, and his power from that of the Father.

"It is prepared" is from hetoimazô, which means "to make ready," and "to prepare." It has the sense of specifically being preparing for a journey or a reception.
