The Jesus is walking on his way to Jerusalem

Matthew 20:17-19
Now Jesus was going up to Jerusalem. On the way, he took the Twelve aside and said to them,  “We are going up to Jerusalem, and the Son of Man will be delivered over to the chief priests and the teachers of the law. They will condemn him to death  and will hand him over to the Gentiles to be mocked and flogged and crucified. On the third day he will be raised to life!
Jesus again predicts His death. This is the third times.
Why?
Jesus knew what will be happened, but he was so calm and obeyed his mission to Jerusalem.
All of his prediction are come truth. He is the Son of God, Son of Man, be crucified and raised to life three days later.
Only Jesus can conquer the death, so He is my savior and my God.
How?
Jesus saw his way is difficulty but he was courage to face it and walked on it.
