In the film Amadeus, F. Murray Abraham plays a composer who all his life is tortured by the greatness of his contemporary Wolfgang Amadeus Mozart. His envy drives him mad. Why wouldn’t God allow him to occupy that place of greatness? In Genesis 21 we find a similar scene: Ishmael, the older half brother of the promised child Isaac, envies his place of blessing. And, through him we get a glimpse of our own hearts.
