This doctrine is the head and the cornerstone. It alone begets, nourishes, builds, preserves, and defends the church of God; and without it the church of God cannot exist for one hour. What Luther Says: An Anthology Vol 2 (704)
how richly does he supply us with the means of contemplating his mercy when, as frequently happens, he continues to visit miserable sinners with unwearied kindness, until he subdues their depravity, and woos them back with more than a parent's fondnessInstitutes, Book 1 Chapter 6
God preordained, for his own glory and the display of His attributes of mercy and justice, a part of the human race, without any merit of their own, to eternal salvation, and another part, in just punishment of their sin, to eternal damnation. Institutes Lib. III. c. 21,5(Opera, Vol. II. pp. 682, GS3)
The distinction is, that to the Father is attributed the beginning of action, the fountain and source of all things; to the Son, wisdom, counsel, and arrangement in action, while the energy and efficacy of action is assigned to the Spirit.Institutes, Book 1 Chapter 13
Justification is a judicial act of God, in which He declares, on the basis of the righteousness of Jesus Christ, that all the claims of the law are satisfied with respect to the sinner.Systematic Theology, 513
Christ in fact had not the least intent of making any change or innovation in the precepts of the law. God there appointed once for all a rite of life which he will never repent of... so let us have no more of that error, that here a defect of the law is corrected by Christ; Christ is not to be made into a new law-giver, adding anything to the everlasting righteousness of his Father, but is to be given the attention of a faithful interpreter, teaching us the nature of the law, its object and its scope.
faith is tossed about by various doubts, so that the minds of the godly are rarely at peace - at least they do not always enjoy a peaceful state. But whatever siege engines may shake them, they either rise up out of the very gulf of temptations, or stand fast upon their watch.
It is therefore faith alone which justifies, and yet the faith which justifies is not alone: just as the heat alone of the sun which warms the earth, and yet in the sun it is not alone, because it is constantly conjoined with light.
There is but one family which ought to be reckoned, both in heaven and on earth, both among angels and among men—if we belong to the Body of Christ. For outside of Him there is nothing but dispersion
the Article of justification is the Master and the prince, the lord, the ruler, and judge, over all the kinds of doctrine, which preserves and governs the entire church doctrine and sets up our conscience in the sight of God.
By the "wisdom of God," he designates this magnificent theater of heaven and earth replenished with numberless wonders, the wise contemplation of which should have enabled us to know God. But this we do with little profit; and therefore he invites us to faith in Christ--faith which, by a semblance of foolishness, disgusts the unbeliever.Institutes, Book 2, Chapter 6
The first part of a good work is the will, the second is vigorous effort in the doing of it. God is the author of both. It is, therefore, robbery from God to arrogate anything to ourselves, either in the will or the act.Institutes, Book 2, Chapter 3
If we can no more bear fruit of ourselves than a vine can bud when rooted up and deprived of moisture, there is no longer any room to ask what the aptitude of our nature is for good.Institutes, Book 2, Chapter 3
even infants bringing their condemnation with them from their mother's womb, suffer not for another's, but for their own defect. For although they have not yet produced the fruits of their own unrighteousness, they have the seem implanted in them. No, their whole nature is, as it were, a seed-bed of sin, and therefore cannot but be odious and abominable to God.Institutes, Book 2 Chapter 1
(such is our innate pride) we always seem to ourselves just, and upright, and wise, and holy, until we are convinced, by clear evidence, of our injustice, vileness, folly, and impurity. Convinced, however, we are not, if we look to ourselves only, and not to the Lord also- he being the only standard by the application of which this conviction can be produced.Institutes, Book 1 Chapter 1
men are never duly touched and impressed with a conviction of their insignificance, until they have contrasted themselves with the majesty of God.Institutes, Book 1 Chapter 1
Let us remember that our justification means not only that our sins are forgiven and that we have been declared to be righteous by God Himself, not merely that we were righteous at that moment when we believed, but permanently righteous.Spiritual Depression (74)
It is its conviction that there is nothing in us or done by us, at any stage of our earthly development, because of which we are acceptable to God. We must always be accepted for Christ's sake, or we cannot ever be accepted at all. This is not true of us only 'when we believe.' It is just as true after we have believed. It will continue to be true as long as we live. Our need of Christ does not cease with our believing; nor does the nature of our relation to Him or to God through Him ever alter, no matter what our attainments in Christian graces or our achievements in Christian behavior may be. It is always on His blood and righteousness alone that we can rest.Miserable-Sinner Christianity in the Hands of the Rationalists, chapter III in Perfectionism, Part One, vol. 7 of The Works of Benjamin B.
