Book IV Chapter XXXVII.-Men are Possessed of Free Will, and Endowed with the Faculty of Making a Choice. It is Not True, Therefore, that Some are by Nature Good, and Others Bad.
1. This expression [of our Lord], "How often would I have gathered thy children together, and thou wouldest not,"597 set forth the ancient law of human liberty, because God made man a free [agent] from the beginning, possessing his own power, even as he does his own soul, to obey the behests (ad utendum sententia) of God voluntarily, and not by compulsion of God. For there is no coercion with God, but a good will [towards us] is present with Him continually. And therefore does He give good counsel to all. And in man, as well as in angels, He has placed the power of choice (for angels are rational beings), so that those who had yielded obedience might justly possess what is good, given indeed by God, but preserved by themselves. On the other hand, they who have not obeyed shall, with justice, be not found in possession of the good, and shall receive condign punishment: for God did kindly bestow on them what was good; but they themselves did not diligently keep it, nor deem it something precious, but poured contempt upon His super-eminent goodness. Rejecting therefore the good, and as it were spuing it out, they shall all deservedly incur the just judgment of God, which also the Apostle Paul testifies in his Epistle to the Romans, where he says, "But dost thou despise the riches of His goodness, and patience, and long-suffering, being ignorant that the goodness of God leadeth thee to repentance? But according to thy hardness and impenitent heart, thou treasurest to thyself wrath against the day of wrath, and the revelation of the righteous judgment of God." "But glory and honour," he says, "to every one that doeth good."598 God therefore has given that which is good, as the apostle tells us in this Epistle, and they who work it shall receive glory and honour, because they have done that which is good when they had it in their power not to do it; but those who do it not shall receive the just judgment of God, because they did not work good when they had it in their power so to do.
2. But if some had been made by nature bad, and others good, these latter would not be deserving of praise for being good, for such were they created; nor would the former be reprehensible, for thus they were made [originally]. But since all men are of the same nature, able both to hold fast and to do what is good; and, on the other hand, having also the power to cast it from them and not to do it,-some do justly receive praise even among men who are under the control of good laws (and much more from God), and obtain deserved testimony of their choice of good in general, and of persevering therein; but the others are blamed, and receive a just condemnation, because of their rejection of what is fair and good. And therefore the prophets used to exhort men to what was good, to act justly and to work righteousness, as I have so largely demonstrated, because it is in our power so to do, and because by excessive negligence we might become forgetful, and thus stand in need of that good counsel which the good God has given us to know by means of the prophets.
3. For this reason the Lord also said, "Let your light so shine before men, that they may see your good deeds, and glorify your Father who is in heaven."599 And, "Take heed to yourselves, lest perchance your hearts be overcharged with surfeiting, and drunkenness, and worldly cares."600 And, "Let your loins be girded about, and your lamps burning, and ye like unto men that wait for their Lord, when He returns from the wedding, that when He cometh and knocketh, they may open to Him. Blessed is that servant whom his Lord, when He cometh, shall find so doing."601 And again, "The servant who knows his Lord's will, and does it not, shall be beaten with many stripes."602 And, "Why call ye me, Lord, Lord, and do not the things which I say? "603 And again, "But if the servant say in his heart, The Lord delayeth, and begin to beat his fellow-servants, and to eat, and drink, and to be drunken, his Lord will come in a day on which he does not expect Him, and shall cut him in sunder, and appoint his portion with the hypocrites."604 All such passages demonstrate the independent will605 of man, and at the same time the counsel which God conveys to him, by which He exhorts us to submit ourselves to Him, and seeks to turn us away from [the sin of] unbelief against Him, without, however, in any way coercing us.
4. No doubt, if any one is unwilling to follow the Gospel itself, it is in his power [to reject it], but it is not expedient. For it is in man's power to disobey God, and to forfeit what is good; but [such conduct] brings no small amount of injury and mischief. And on this account Paul says, "All things are lawful to me, but all things are not expedient; "606 referring both to the liberty of man, in which respect "all things are lawful," God exercising no compulsion in regard to him; and [by the expression] "not expedient" pointing out that we "should not use our liberty as a cloak of maliciousness,607 for this is not expedient. And again he says, "Speak ye every man truth with his neighbour."608 And, "Let no corrupt communication proceed out of your mouth, neither filthiness, nor foolish talking, nor scurrility, which are not convenient, but rather giving of thanks."609 And, "For ye were sometimes darkness, but now are ye light in the Lord; walk honestly as children of the light, not in rioting and drunkenness, not in chambering and wantonness, not in anger and jealousy. And such were some of you; but ye have been washed, but ye have been sanctified in the name of our Lord."610 If then it were not in our power to do or not to do these things, what reason had the apostle, and much more the Lord Himself, to give us counsel to do some things, and to abstain from others? But because man is possessed of free will from the beginning, and God is possessed of free will, in whose likeness man was created, advice is always given to him to keep fast the good, which thing is done by means of obedience to God.
