Afraid to ask
Mark 9:30 And they departed thence, and passed through Galilee; and he would not that any man should know it.
They passed secretly through Galilee, probably because he did not want to be delayed getting to Jerusalem.
Mark 9:31 For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day.
The reason for going to Jerusalem was to do what he was sent for: to die on the cross for our sins and to rise on the third day. I suppose most people think they are going to heaven, but do they know how? Jesus is the way, believe on him.
Mark 9:32 But they understood not that saying, and were afraid to ask him.
They did not understand yet, and were afraid to ask. Do not be afraid to ask Jesus for understanding. Do not be afraid to ask about Jesus. For some reason that name is off limits. No, that name must be spoken and received. The devil wants to keep this silent, we must speak the name of Jesus.
