Nobody likes prophets.
Prophets tell us things that we would rather not hear. They take the side of issues that we find uncomfortable because they have a view of the world and of God that the rest of us don't have. Because of that they are rarely loved by the masses while they are alive, but then when they are gone people remember them and quote them. Take Martin Luther King, Jr. for example. Today his words are familiar and beloved, but when he said them things were different.
