A man, in mind and affections, may depart from that which yet will
not depart from him, yea, a man in mind may depart from that which
yet will dwell in him as long as he lives.
For instance, there are many diseases that cleave to men, from which
in their minds they willingly depart; yea, their greatest
disquietment is, that so bad a distemper will abide by them; and
might they but have their desire accomplished, they would be as far
therefrom as the ends of the earth are asunder: and while they are
found to continue together, the mind departs therefrom, and is gone
either to God or to physicians for help and deliverance from it.
And thus it is with the saint, and should be with every one that by
way of profession nameth the name of Christ, Rom. 7; he should
depart from his indwelling sin with his mind: "With his mind he
should serve the law of God."
