A treatise of original sin ... proving that it is

Lastly, The Naturality of this evil doth appear In the great easiness, promptitude §10and delight a man naturally finds to sin. This is a way to discover what is natural, if the actions be easy, ready, and with delight; This discovers they flow from Nature, but what is of art, that is with difficulty, and much observation. We need not hire, or teach a man to eat or drink, these are natural actions, and are accompanied with delight: And thus the Naturality of this birth-sin is notably manifested; with what ease, pleasure, and inward readiness is a man carried out to sin from his youth up: Eliphaz speaks notably of this, Job 15. 16. How much more abominable and filthy is man, which drinketh iniquity like water, like a Leviathan, that is said to drink up the river, and hasteth not. You see he calls every man by nature abominable and filthy, which is discovered by this, He drinketh iniquity like water, as a dropsy, or feverish man, that is scorched with heat within, doth with greediness and delight pour down water, and the more he drinketh, the thirstier he is, and he never saith he hath enough. Thus it is with filthy and corrupted man, he doth with earnestness and delight fulfil the lust of the flesh, he is never satisfied. Every man in the world hath a Sheol within him, that is always craving, and saying, Give, Give, as hell hath unquenchable sparks of fire, such an hell is in every mans heart; As our Saviour said, It's my meat and drink to do my Fathers will. Thus it is every mans meat and drink by nature to be doing the Devils will: Do ye not see it in children, how of themselves they are prone to any impiety, but call them to learn, or to be instructed, then there is much averseness? All this ariseth from the natural evil within us.
