Deuteronomy 18:15 "You shall listen to him"

Children obey their parents. Students listen to their teachers. Players carry out the instructions of their coach. Hikers follow their leader.

We all have our goals and are guided by those who help us to reach them.

The Jewish people's goal is to fulfill the will of HaShem as stated in the Torah.

HaShem chooses a specific person and appoints him as a prophet.

His job is to help the people in explaining the ways of the Torah and to encourage them to fulfill the Mitzvot.

We are commanded to listen to the prophet and obey his instructions.
