Jesus was very happy to know that the disciples
had recognized who He really was. But even
though they knew that He was the Son of God,
He also knew that they had little concept of the
way His mission to the world was to be carried
out.

He started by trying to change their minds of
their hope of an earthly kingdom. He had already
hinted of the fact that death awaited Him (John
2:19; 3:14) but they had missed the meaning
altogether.

Then He plainly told them what was going to
happen, how that He would be rejected by the
rulers, be killed and would arise on the third day.
