“You see how rich the Christian is,” he says, “since, even should he desire it, he is unable to forfeit his salvation, no matter how many sins he may commit, unless indeed he refuses to believe (‘_nisi nolit credere_’). No sin but unbelief can bring him to damnation; everything else is at once swept away by this faith, so soon as he returns to it, or recollects the Divine promise made to the baptised.”[548] “Christ’s Evangel is indeed a mighty thing.... God’s Word brings everything to pass speedily, bestows forgiveness of sins and the gift of eternal life; and the cost of this is merely that you should hear the Word, and after hearing it believe. If you believe, then you possess it without any trouble, expense, delay or difficulty.”[549] “No other sin exists in the world save unbelief. All others are mere trifles, as when my little Hans or Lena misbehave themselves in the corner, for we all take that as a big joke. In the same way faith covers the stench of our filth before God.... All sins shall be forgiven us if only we believe in the Son.”[550] “As I have often said, the Kingdom of Christ is nothing else but forgiveness and perpetual blotting out of sin, which is extinguished, covered over, swept away and made clean while we are living here.” “Christ makes things so easy for us who stand before God in fear and trembling.”[551] “_Summa summarum_: Our life is one long ‘_remissio peccatorum_,’ and forgiveness of sin, otherwise it could not endure.”[552] Here, indeed, we have one of the main props of Luther’s practical theology. To this the originator of the doctrine sought to remain faithful to the very end of his life, whereas certain other points of his teaching he was not unwilling to revise. His ideas on sin and repentance had sprung originally from his desire to relieve his own conscience,[553] and, of this, they ever retained the mark. The words and doctrine of a teacher are the best witnesses we have to his moral character, and here the doctrine is one which affords but little stimulus to virtue and Christian perfection, but rather the reverse. In what follows we shall consider more closely the relation between this doctrine and the effort after virtue, while at the same time taking into account that passivity, nay, entire unfreedom of the will for doing what is good, proclaimed by Luther. _Luther on Efforts after Higher Virtue._ The effort to attain perfection and to become like to Christ, which is the highest aim of the Christian, is scarcely promoted by making the whole Gospel to consist merely in the happy enjoyment of forgiveness. The hard work required for the building up of a truly virtuous life on the rude soil of the world, necessarily involving sacrifice, self-denial, humiliation and cheerful endurance of suffering, was more likely to be looked at askance and carefully avoided by those who clung to such a view.
