The settings and conditions differ, so the expectations also should differ. Children are like young plants, and teaching them knowledge is to children as rain is to plants. Some need special care and some are hardy. Others may need transplanting, support and more sun and water. Some plants may need grafting, transplanting, thinning, support or other intervention to help them bear good fruit.
Prophets change the people and the world by their lives and their words.
They give the law, bring knowledge and spirit from a higher power, prepare their followers for the future, are saintly and perform a host of other functions that might be similar to a teacher's role. Some aspects of the prophets' practices that teachers might reflect upon are that prophets teach and show love, but have high expectations for behavior. They are authorities in this world, but they represent a higher power who is the ultimate lawgiver and judge. Prophets take humanity from its limited beliefs to a higher and richer life. This is not usually appreciated by humanity, who in turn persecutes the prophet and belittles his teachings.
