But what sort of shepherds are they who for fear of giving offense not only fail to prepare the sheep for the temptations that threaten, but even promise them worldly happiness? God himself made no such promise to this world. On the contrary, God foretold hardship upon hardship in this world until the end of time. And you want the Christian to be exempt from these troubles? Precisely because he is a Christian, he is destined to suffer more in this world.

Augustine, from a sermon on pastors, via David Mahfood.
