Mark 9:32 But they understood not that saying, and were afraid to ask him.
Jesus was telling them clearly that He would die, be buried, and then rise from the dead. They heard the words but did not understand them. They were afraid to ask.
It will be after the resurrection before they understand some of the basic things that they were told. Most of the time we need enough life to understand so many truths. We can understand the theory but not the real truth of the matter.
So as you study the Bible do not be afraid to ask the Holy Spirit to teach you. Do not be afraid to go find someone who knows more than you and ask. Learn. Take the risk of looking foolish but ask. Do not let your pride stand in the way of your learning the truths you need to know.
Also as you disciple be sure to know that others are afraid to ask. You will have to work at letting them know that you are willing to be questioned. Let them know that you will not think less of them or make fun of them.
They need to ask but are afraid. Give them the liberty to ask.
