I found this little gem of a quote by David Powlison, Christian Counselor and adjunct Professor at Westminster College.
People follow the desires of body and mind (see Eph. 2:3). Bodily appetites–the organism’s hedonistic instinct to feel good–are certainly powerful masters unto sin. But desires of the mind–for power, human approval, success, preeminence, wealth, self-righteousness, and so forth–are also potent masters. The desires of the mind often present the most subtle and deceitful lusts because the outworkings are not always obvious. They don’t reside in the body, but the Bible still views them as “lusts.”
