2. Since, however, there will be occasion to treat of the doctrine of repentance in some chapters of this Second Book, I shall now give some account of the whole method into which this Book is digested. As the main design of the First Book was to lay open the nature of Original Sin, and the deadly influence which it has upon all our actions; so it is but fit that the Second Book should begin with JESUS CHRIST, that everlasting wellspring of man’s salvation, in whom alone we find help and a remedy against the destructive poison of Original Sin, and against that flood of calamities and miseries which thence proceeds. All this on man’s side, is effected by FAITH, apprehending that salvation which is merited by Christ. This matter is explained in the first three chapters of this Book. As, however, that _faith_ which leads the soul to this fountain, and draws thence effects so excellent and good, also brings forth living and sound _fruits_; the next three chapters (IV-VI), are spent in describing the same more at large. But, even as the fruits of righteousness and of the Spirit are to grow up in us and wax strong, so must the fruits of the flesh, in proportion, decay and decrease. And this is the daily, effectual, and unfeigned repentance, wherein a Christian ought constantly to be employed, if ever the flesh be mortified, and the Spirit be restored to dominion. It was, therefore, judged expedient, to give here a clear description of the difference betwixt the flesh and the Spirit, and of the properties of a daily repentance. Here consult Chapters VII-X. But inasmuch as from this habitual repentance, and the mortification of the _old_ man (the life of a true Christian being nothing else but a constant crucifixion of the flesh), the _new_ man is daily to come forth, it is impossible to find a more perfect pattern, than that which our Lord Jesus Christ himself has left us. And for this reason, the life of Christ ought to be a mirror unto us, in which to view ourselves and him; and by beholding him, to embrace the more freely his poverty and reproach, his contempt and sorrow, his cross and passion, his agony and death. And this holy life of Christ is the death of the flesh, and is accompanied with the exercise of prayer, love, and humility. This is set forth at large in Chapters XI-XXV.
