'A guilty sinner carries a witness against himself in his own bosom. It was guilty Herod cried out, "John the Baptist is risen from the dead." Such a conscience is the devil's anvil, on which he fabricates all those swords and spears with which the guilty sinner pierces himself. Guilt is to danger, what fire is to gun-powder: a man need not fear to walk among many barrels of powder, if he have no fire about him.'
John Flavel, Keeping the Heart, p.56.
