That the beginning of our good will and its completion comes from God.
And this plainly teaches us that the beginning of our good will is given to us by the inspiration of the Lord, when He draws us towards the way of salvation either by His own act, or by the exhortations of some man, or by compulsion; and that the consummation of our good deeds is granted by Him in the same way: but that it is in our own power to follow up the encouragement and assistance of God with more or less zeal, and that accordingly we are rightly visited either with reward or with punishment, because we have been either careless or careful to correspond to His design and providential arrangement made for us with such kindly regard. And this is clearly and plainly described in Deuteronomy. “When,” says he, “the Lord thy God shall have brought thee into the land which thou art going to possess, and shall have destroyed many nations before thee, the Hittite, and the Gergeshite, and the Amorite, the Canaanite, and the Perizzite, the Hivite, and the Jebusite, seven nations much more numerous than thou art and stronger than thou, and the Lord thy God shall have delivered them to thee, thou shalt utterly destroy them. p. 329 Thou shalt make no league with them. Neither shalt thou make marriage with them.” 1279 So then Scripture declares that it is the free gift of God that they are brought into the land of promise, that many nations are destroyed before them, that nations more numerous and mightier than the people of Israel are given up into their hands. But whether Israel utterly destroys them, or whether it preserves them alive and spares them, and whether or no it makes a league with them, and makes marriages with them or not, it declares lies in their own power. And by this testimony we can clearly see what we ought to ascribe to free will, and what to the design and daily assistance of the Lord, and that it belongs to divine grace to give us opportunities of salvation and prosperous undertakings and victory: but that it is ours to follow up the blessings which God gives us with earnestness or indifference. And this same fact we see is plainly taught in the healing of the blind men. For the fact that Jesus passed by them, was a free gift of Divine providence and condescension. But the fact that they cried out and said “Have mercy on us, Lord, thou son of David,” 1280 was an act of their own faith and belief. That they received the sight of their eyes was a gift of Divine pity. But that after the reception of any blessing, the grace of God, and the use of free will both remain, the case of the ten lepers, who were all healed alike, shows us. For when one of them through goodness of will returned thanks, the Lord looking for the nine, and praising the one, showed that He was ever anxious to help even those who were unmindful of His kindness. For even this is a gift of His visitation; viz., that he receives and commends the grateful one, and looks for and censures those who are thankless.
