Wherein the truth of predestination and grace is defended against the semi-Pelagians,—those people to wit, who by no means withdraw altogether from the Pelagian heresy, in that they contend that the beginning of salvation and of faith is of ourselves; so that in virtue, as it were, of this precedent merit, the other good gifts of God are attained. Augustin shows that not only the increase, but the very beginning also of faith is in God’s gift. On this matter he does not disavow that he once thought differently, and that in some small works, written before his episcopate, he was in error, as in that exposition, which they object to him, of propositions from the epistle to the Romans.

In the first part of the book he proves that the perseverance by which a man perseveres in Christ to the end is God's gift; for that it is a mockery to ask of God that which is not believed to be given by God. Moreover, that in the Lord's prayer scarcely anything is asked for but perseverance, according to the exposition of the martyr Cyprian, by which exposition the enemies to this grace were convicted before they were born.

We know that in the Epistle to the Philippians the apostle said, "To write the same things to you to me indeed is not grievous, but for you it is safe;" yet the same apostle, writing to the Galatians, when he saw that he had done enough among them of what he regarded as being needful for them, by the ministry of his preaching, said, "For the rest let no man cause me labour," or as it is read in many codices, "Let no one be troublesome to me." But although I confess that it causes me trouble that the divine word in which the grace of God is preached (which is absolutely no grace if it is given according to our merits), great and manifest as it is, is not yielded to, nevertheless my dearest sons, Prosper and Hilary, your zeal and brotherly affection-which makes you so reluctant to see any of the brethren in error, as to wish that, after so many books and letters of mine on this subject, I should write again from here-I love more than I can tell, although I do not dare to say that I love it as much as I ought. Wherefore, behold, I write to you again. And although not with you, yet through you I am still doing what I thought I had done sufficiently.

I Wrote again to the same persons another treatise, which I entitled On Rebuke and Grace, because I had been told that someone there had said that no man ought to be rebuked for not doing God's commandments, but that prayer only should be made on his behalf, that he may do them. This book begins on this wise, "I have read your letters, dearly beloved brother Valentine."

Wherein the truth of predestination and grace is defended against the semi-Pelagians, --those people to wit, who by no means withdraw altogether from the Pelagian heresy, in that they contend that the beginning of salvation and of faith is of ourselves; so that in virtue, as it were, of this precedent merit, the other good gifts of God are attained. Augustin shows that not only the increase, but the very beginning also of faith is in God's gift. On this matter he does not disavow that he once thought differently, and that in some small works, written before his episcopate, he was in error, as in that exposition, which they object to him, of propositions from the epistle to the Romans. But he points out that he was subsequently convinced chiefly by this testimony, "but what hast thou that thou hast not received?" which he proves is to be taken as a testimony concerning faith itself also. He says that faith is to be counted among other works, which the apostle denies anticipating God's grace when He says, "not of works." He declares that the hardness of the heart is taken away by grace, and that all come to Christ who are taught to come by the Father; but that those whom He teaches, He teaches in mercy, while those whom He teaches not, in judgment He teaches not.

In this book, John Colquhoun helps us understand the importance of knowing the relationship between law and gospel. Colquhoun especially excels in showing how important the law serves as a believer’s rule of life without compromising the freeness and fullness of the gospel. In one of the greatest Reformed studies of the topic, Colquhoun encourages believers to combat legalism and antinomianism by joyfully embracing a correct view of the law.
