Although God created man upright and perfect, and gave him a righteous law, which had been unto life had he kept it, and threatened death upon the breach thereof, yet he did not long abide in this honour; Satan using the subtlety of the serpent to subdue Eve, then by her seducing Adam, who, without any compulsion, did willfully transgress the law of their creation, and the command given unto them, in eating the forbidden fruit, which God was pleased, according to his wise and holy counsel to permit, having purposed to order it to his own glory.

From this original corruption, whereby we are utterly indisposed, disabled, and made opposite to all good, and wholly inclined to all evil, do proceed all actual transgressions.
Rom 8.7, Col 1.21, James 1.14-James 1.15, Matt 15.19
The corruption of nature, during this life, doth remain in those that are regenerated; and although it be through Christ pardoned and mortified, yet both itself, and the first motions thereof, are truly and properly sin.
