'The impious cannot enjoy that they have, partly because they receive it not as at God's hands, which only consideration maketh temporal blessings comfortable, and partly because through error, placing it above things of far more price and worth, they turn that to poison which might be food, they make their prosperity their own snare; in the nest of their highest growth they lay foolishly those eggs out of which their woful overthrow is afterwards hatched.' (Hooker, Laws of Ecclesiastical Polity, Volume II, 415-416)
