Let each one of us, then, proceed according to the measure of his puny capacity and set out upon the journey we have begun. No one shall set out so inauspiciously as not daily to make some headway, though it may be slight. Therefore, let us not cease so to act that we may make some unceasing progress in the way of the Lord. And let us not despair at the slightness of our success; for even though attainment may not correspond to desire, when today outstrips yesterday, the effort is not lost. Only let us look toward our mark with sincere simplicity and aspire to our goal; not fondly flattering ourselves, nor excusing our own evil deeds, but with continuous effort striving toward this end: that we may surpass ourselves in goodness until we attain to goodness itself.
-John Calvin, Institutes of the Christian Religion, 3.6.5
When I was younger, I gave myself overmuch to human teaching, like others of my day, and when about seven or eight years ago I undertook to devote myself entirely to the Scriptures I was always prevented by philosophy and theology. But eventually I came to the point where led by the Word and Spirit of God I saw the need to set aside all these things and to learn the doctrine of God direct from his own Word. Then I began to ask God for light and the Scriptures became far clearer to me.
–Bromiley, Zwingli and Bullinger, 90-91 (as cited in George, Theology of the Reformers).
In his Theology of the Reformers, Timothy George recounts, through Luther’s own words, the seminal discovery that changed church history and the world as we know it:
Near the end of his life, Luther remembered how as a monk the phrase “justice of God” in Rom 1:17 had struck terror in his soul. All of his attempts to satisfy God–his prayers, fastings, vigils, good works–left him with a wholly disquieted conscience. His mood swung from despair over his own failures to a simmering rage at God: “I did not love, indeed I hated, that God who punished sinners; and with a monstrous, silent, if not blasphemous, murmuring I fumed against God.” Still, he “knocked persistently upon Paul,” meditating day and night in his study in the tower, until
I began to understand that the “justice of God” meant that justice by which the just man lives through God’s gift, namely by faith. This is what it means: the justice of God is revealed by the gospel, a passive justice with which the merciful God justifies us by faith, as it is written: “He who through faith is just shall live.” Here I felt that I was altogether born again and had entered paradise itself through open gates.
