"A man naturally fancies that it is his own exceeding love of virtue that makes him not able to bear with those that want it. And when he abhors one man, despises another, and can't bear a third, he supposes it all to be a proof of his own high sense of virtue and just hatred of sin. And yet one would think that a man needed no other cure for this temper than this one reflection: that if this had been the spirit of the Son of God, if he had hated sin in this manner, there [would have] been no redemption of the world; that if God had hated sinners in this manner day and night, the world itself [would have] ceased long ago. This, therefore, we may take for a certain rule: that the higher our sense of virtue is, the more we shall have compassion on those who lack it."
- William Law, from A Serious Call to a Devout and Holy Life
