It is illicit, not only to give consent to evil, but also to have an inclination, or propensity to such consent: because all our powers ought to be carried toward the good.

We again regard it as sin whenever man is influenced in any degree by any desire contrary to the law of God; nay, we maintain that the very pravity which begets in us such desires is sin.

Lust in the bud; that is, the first risings of lust, even before the consent of the will to them; the first openings of particular lusts, sometimes not regarded nor noticed, and so neither approved nor disapproved; and sometimes checked in their very rising, Rom. 7:15. But however it be, they are sins here forbidden, though the Papists will not allow them to be so

We hold that all human desires are evil, and we charge them with sin not in as far as they are natural, but because they are inordinate, and inordinate because nothing pure and upright can proceed from a corrupt and polluted nature.

But Protestants also believe that lust or concupiscence in the regenerate, as including a remaining tendency towards what is sinful, and the first or earliest motions of this tendency in the heart, though not deliberately consented to and followed out, is itself truly and properly sinful.
