The prophets are God’s messengers. Many of us cannot hear the voice of our souls nor see God’s signs. So God sends His prophets to remind us of our purpose, to teach us of virtue and vice, and to guide us to the straight path. He sends His prophets to teach us that we are responsible for our own actions and that when we sin we harm only ourselves. A child burns himself rather than his parent when he places his hand in a fire.
