XXII. Since the movement of the soul is self-originated, the grace of God demands from it what the soul possesses, willingness as its contribution to salvation. For the soul wishes to be its own good; which the Lord, however, gives it. For it is not devoid of sensation so as to be carried along like a body. Having is the result of taking, and taking of willing and desiring; and keeping hold of what one has received, of the exercise of care and of ability. Wherefore God has endowed the soul with free choice, that He may show it its duty, and that it choosing, may receive and retain.
