An exposition with practical observations continued upon the fourth, fifth, sixth, and seventh chapters…

It was the ancient error of the Pelagians, that the sin of man came only by imitation: they denied that man had a stock of corruption in his nature, or that his nature was corrupted; but, seeing others sin, he sinned; an opinion which carries its condemnation in its own face, as well as in our hearts. And though similitudes are no proofs, yet, the reason of a similitude is: mans sinning is therefore compared to a sparks flying, to show how naturally he sins. A spark flies upward without any to lead it the way; and a bird would fly, though she should never see another bird fly: And if a man could live so, as never to see any one example of sin all his days, yet that man, out of his own heart, might bring forth every sin, every day. Example quickens and encourages the principles of sin within us, but we can sin without any extrinsic motion or provocation, without pattern or president from without. Lastly observe,

Example quickens and encourages the principles of sin within us, but we can sin without any extrinsick motion or provocation, without pattern or president from without. Lastly observe,

To sin, is no burden or labour to a natural man: For it is his nature. It is no pains to the spark, to fly upwards: what we do naturally, we do easily. Holy duties are no burdens to a godly man, because, through grace, he doth them naturally; he hath an inward principle, which dictates the law of holiness to him, though he should want outward teaching: He hath an unction from the holy Ghost, and knoweth all things,
