| WHEN it is said that it is in the power of free will to avoid putting obstacles to grace, that saying is to be understood of those in whom the natural faculty is unimpaired by sin. But if the will has fallen into evil courses by some previous inordinate act, it will not be altogether in its power to avoid putting obstacles in the way of grace. For though for some momentary occasion it may abstain from some particular act of sin by its own power, nevertheless, if left long to itself, it will fall into sin; and by sin an obstacle is put to grace. For when the mind of man turns aside from the state of righteousness, it clearly puts itself out of relation with its due end. Thus what ought to be the prime object of its affections, as being its last end, comes to be less loved than that other object to which it has inordinately turned, making of it another last end. Whatever in such a posture of the mind occurs to fit in with the inordinate end, however inconsistent with the due end, will be chosen, unless the will be brought back to due order, so as to prefer the due end to all others, and that is an effect of grace. But the choice of anything inconsistent with the last end puts an obstacle in the way of grace, as grace goes to turn one in the direction of the end. Hence after sin a man cannot abstain from all further sin before by grace he is brought back to due order. | |
