The role of Prophets and Messengers in general, and the Prophet Muhammad in specific, is to make clear and plain:
- Who God Is.
- What God wants from us and how we are to go about doing it.
- What is the nature of reality beyond what we can sense-perceive.
The Prophet, in essence, makes God accessible for us by demonstrating through his blessed lifestyle (read Sunnah, how one conceives of and worships God, with certainty of method and ritual.
لَقَد كانَ لَكُم في رَسولِ اللَّهِ أُسوَةٌ حَسَنَةٌ لِمَن كانَ يَرجُو اللَّهَ وَاليَومَ الآخِرَ وَذَكَرَ اللَّهَ كَثيرًا
“You have an excellent model in the Messenger of Allah, for all who put their hope in Allah and the Last Day and remember Allah much.” Qur’an, 33:21
