Luther rejoices in the doctrine of sola gratia because it alone is able to engender assurance of salvation. He writes: "As for myself, I certainly confess that, if such a thing could somehow be, I should be unwilling to have free will given me, or anything left in my own hand, which might enable me to make an effort at salvation; not only because in the midst of so many dangers and adversities and also of so many assaulting devils I should not be strong enough to remain standing and keep my hold of it (for one devil is mightier than all men put together, and not a single man would be saved), but because, even if there were no dangers and no adversities and no devils, I should still be compelled to toil forever uncertainly, and to beat the air in my struggle. For though I should live and work to eternity, my own conscience would never be sure and at ease as to how much it ought to do in order to satisfy God. No matter how perfect a work might be, there would be left a doubt whether it pleased God, or whether He required anything more, as is proved by the experience of all who endeavor to be saved by the Law (iustitiariorum), and as I, to my own great misery, have learned abundantly during so many years. But now, since God has taken my salvation out of the hands of my will, and placed it into those of His own and has promised to save me, not by my own work or running, but by His grace and mercy, I feel perfectly secure, because He is faithful and will not lie to me; moreover, He is powerful and great, so that neither devils nor adversities can crush Him, or pluck me out of His hand. No one, says He, shall pluck them out of My hand; for My Father, who gave them unto Me, is greater than all. Thus it comes to pass that, though not all are saved, at least some, nay, many are, whereas by the power of free will absolutely none would be saved, but every one of us would be lost. We are also certain and sure that we please God, not by the merit of our own work, but by the favor of His mercy which He has promised us, and that, if we have done less than we ought, or have done anything amiss, He does not impute it to us, but, as a father, forgives and amends it. Such is the boast of every saint in his God." (E. 362; St. L. 1961f.)
In the Apology of the Augsburg Confession this thought of Luther's is repeated as follows: "If the matter [our salvation] were to depend upon our merits, the promise would be uncertain and useless, because we never could determine when we would have sufficient merit. And this experienced consciences can easily understand [and would not, for a thousand worlds, have our salvation depend upon ourselves]." (CONC. TRIGL. 145, 84; compare 1079, 45f.)
243. Truth of God's Majesty Serves God's Gracious Will.
Luther regarded the teaching that everything is subject to God's majesty as being of service to His gracious will. We read: "Two things require the preaching of these truths [concerning the infallibility of God's foreknowledge, etc.]; the first is, the humbling of our pride and the knowledge of the grace of God; the second, Christian faith itself. First, God has certainly promised His grace to the humbled, i.e., to those who deplore their sins and despair [of themselves]. But man cannot be thoroughly humbled until he knows that his salvation is altogether beyond his own powers, counsels, efforts, will, and works, and depends altogether upon the decision, counsel, will, and work of another, i.e., of God only. For as long as he is persuaded that he can do anything toward gaining salvation, though it be ever so little, he continues in self-confidence, and does not wholly despair of himself; accordingly he is not humbled before God, but anticipates, or hopes for, or at least wishes for, a place, a time, and some work by which he may finally obtain salvation." (E. 153. 133; St. L. 1715. 1691.) "More than once," says Luther, "I myself have been offended at it [the teaching concerning God's majesty] to such an extent that I was at the brink of despair, so that I even wished I had never been created a man,—until I learned how salutary that despair was and how close to grace." (E. 268; St. L. 1850.)
Of the manner in which, according to Luther, the truth concerning God's majesty serves the Gospel, we read: "Moreover, I do not only wish to speak of how true these things are,… but also how becoming to a Christian, how pious, and how necessary it is to know them. For if these things are not known, it is impossible for either faith or any worship of God to be maintained. That would be ignorance of God indeed; and if we do not know Him, we cannot obtain salvation, as is well known. For if you doubt that God foreknows and wills all things, not contingently, but necessarily and immutably, or if you scorn such knowledge, how will you be able to believe His promises, and with full assurance trust and rely upon them? When He promises, you ought to be sure that He knows what He is promising, and is able and willing to accomplish it, else you will account Him neither true nor faithful. That, however, is unbelief, extreme impiety, and a denial of the most high God. But how will you be confident and sure if you do not know that He certainly, infallibly, unchangeably, and necessarily knows, and wills, and will perform what He promises? Nor should we merely be certain that God necessarily and immutably wills and will perform [what He has promised], but we should even glory in this very thing, as Paul does, Rom. 3, 4: 'Let God be true, but every man a liar.' And again, Rom. 9, 6; 4, 21; 1 Sam. 3, 19: 'Not that the Word of God hath taken none effect.' And in another place, 2 Tim. 2, 19: 'The foundation of God standeth sure, having this seal, The Lord knoweth them that are His.' And in Titus 1, 2: 'Which God, that cannot lie, hath promised before the world began.' And in Heb. 11, 6: 'He that cometh to God must believe that God is, and that He is a rewarder of them that hope in Him.' So, then, Christian faith is altogether extinguished, the promises of God and the entire Gospel fall absolutely to the ground, if we are taught and believe that we have no need of knowing the foreknowledge of God to be necessary and the necessity of all things that must be done. For this is the only and highest possible consolation of Christians in all adversities to know that God does not lie, but does all things immutably, and that His will can neither be resisted, nor altered, nor hindered." (E. 137. 264; St. L. 1695. 1845.)
244. There Are No Real Contradictions in God.
Among the mysteries which we are unable to solve Luther enumerates the questions: Why did God permit the fall of Adam? Why did He suffer us to be infected with original sin? Why does God not change the evil will? Why is it that some are converted while others are lost? We read: "But why does He not at the same time change the evil will which He moves? This pertains to the secrets of His majesty, where His judgments are incomprehensible. Nor is it our business to investigate, but to adore these mysteries. If, therefore, flesh and blood here take offense and murmur, let them murmur; but they will effect nothing, God will not be changed on that account. And if the ungodly are scandalized and leave in ever so great numbers, the elect will nevertheless remain. The same answer should be given to those who ask, 'Why did He allow Adam to fall, and why does He create all of us infected with the same sin when He could have preserved him [Adam], and created us from something else, or after first having purged the seed?' He is God, for whose will there is no cause or reason which might be prescribed for it as a standard and rule of action; for it has no equal or superior, but is itself the rule for everything. If it had any rule or standard, cause or reason, it could no longer be the will of God. For what He wills is right, not because He is or was in duty bound so to will, but, on the contrary, because He wills so, therefore what occurs must be right. Cause and reason are prescribed to a creature's will, but not to the will of the Creator, unless you would set another Creator over Him." (E. 259; St. L. 1840.)
Regarding the question why some are converted while others are not, we read: "But why this majesty does not remove this fault of our will, or change it in all men (seeing that it is not in the power of man to do so), or why He imputes this [fault of the will] to man when he cannot be without it, it is not lawful to search, and although you search much, you will never discover it, as Paul says, Rom. 9, 20: 'O man, who art thou that repliest against God?'" (E. 223, St. L. 1796.) "But as to why some are touched by the Law and others are not, so that the former receive, and the latter despise, the grace offered, this is another question, and one not treated by Ezekiel in this place, who speaks of the preached and offered mercy of God, not of the secret and to-be-feared will of God, who by His counsel ordains what and what kind of persons He wills to be capable and partakers of His preached and offered mercy. This will of God must not be searched, but reverently adored, as being by far the most profound and sacred secret of divine majesty, reserved for Himself alone, and prohibited to us much more religiously than countless multitudes of Corycian Caves." (E. 221; St. L. 1794.)
Christians firmly believe that in His dealings with men God is always wise and just and good. Luther: "According to the judgment of reason it remains absurd that this just and good God should demand things that are impossible of fulfilment by free will, and, although it cannot will that which is good but necessarily serves sin, should nevertheless charge this to free will; and that, when He does not confer the Spirit, He should not act a whit more kindly or more mercifully than when He hardens or permits men to harden themselves. Reason will declare that these are not the acts of a kind and merciful God. These things exceed her understanding too far, nor can she take herself into captivity to believe God to be good, who acts and judges thus; but setting faith aside, she wants to feel and see and comprehend how He is just and not cruel. She would indeed comprehend if it were said of God: 'He hardens nobody, He damns nobody, rather pities everybody, saves everybody,' so that, hell being destroyed and the fear of death removed, no future punishment need be dreaded. This is the reason why she is so hot in striving to excuse and defend God as just and good. But faith and the spirit judge differently, believing God to be good though he were to destroy all men." (E. 252; St. L. 1832.) "The reason why of the divine will must not be investigated, but simply adored, and we must give the glory to God that, being alone just and wise, He does wrong to none, nor can He do anything foolish or rash, though it may appear far otherwise to us. Godly men are content with this answer." (E. 153; St. L. 1714.)
According to Luther, divine justice must be just as incomprehensible to human reason as God's entire essence. We read: "But when we feel ill at ease for the reason that it is difficult to vindicate the mercy and equity of God because He damns the undeserving, i.e., such ungodly men as are born in ungodliness, and hence cannot in any way prevent being and remaining ungodly and damned, and are compelled by their nature to sin and perish, as Paul says [Eph. 2, 3]: 'We were all the sons of wrath even as others,' they being created such by God Himself out of the seed which was corrupted through the sin of the one Adam,—then the most merciful God is to be honored and revered in [His dealings with] those whom He justifies and saves, although they are most unworthy, and at least a little something ought to be credited to His divine wisdom by believing Him to be just where to us He seems unjust. For if His justice were such as could be declared just by human understanding, it would clearly not be divine, differing nothing from human justice. But since He is the one true God, and entirely incomprehensible and inaccessible to human reason, it is proper, nay, necessary, that His justice also be incomprehensible, even as Paul also exclaims, Rom. 11, 33, saying: 'O the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments, and His ways past finding out!' Now, they would not be incomprehensible if we were able, in everything He does, to comprehend why they are just. What is man compared with God? How much is our power capable of as compared with His? What is our strength compared with His powers? What is our knowledge compared with His wisdom? What is our substance compared with His substance? In short, what is everything that is ours as compared with everything that is His?" (E. 363; St. L. 1962.)
