Does he need to die?

I think I know who this man is! We have been traveling for such a long time, and he has been healing lepers, raising people from the dead, and yet I haven't got it. People have been saying he is Elijah, some saying he is John the Baptist, and yet some say he is Jeremiah. I told him this, and he asked who do I think he is. I said that he is the Messiah, son of the living God. He praised me calling me, "Peter" and "the rock on which he will build his church." But He also told me not to tell anyone. Why would he not want to tell anyone? We've been waiting for the Messiah for such a long time, shouldn't we treat this time with praise and joy? And what's this about him having to suffer and die...I would sooner die myself than let him come to harm!
