“For as the surest source of destruction to men is to obey themselves, so the only haven of safety is to have no other will, no other wisdom, than to follow the Lord wherever he leads. Let this then be the first step, to abandon ourselves, and devote the whole energy of our minds to the service of God. By service, I mean not only that which consists in verbal obedience, but that by which the mind, divested of its own carnal feelings, implicitly obeys the call of the Spirit of God. This transformation (which Paul calls the renewing of the mind, Rom. 12:2; Eph. 4:23), though it is the first entrance to life, was unknown to all the philosophers. They give the government of man to reason alone, thinking that she alone is to be listened to; in short, they assign to her the sole direction of the conduct. But Christian philosophy bids her give place, and yield complete submission to the Holy Spirit, so that the man himself no longer lives, but Christ lives and reigns in him (Gal. 2:20).”
