Be careful and don’t refuse to listen when God speaks. Those people (Israelites) refused to listen to him when he warned them on earth. And those people did not escape. Now God is speaking from heaven. So now it will be worse for those people who refuse to listen to him.
If a person refuses to learn, then he is only hurting himself. But the person who listens when someone tells him he is wrong, will understand more and more.
Even wise people should listen to these words. They will learn more and become even wiser. And people who are skilled at solving problems will gain even more understanding.
