The author presents a close reading of Martin Luther's lectures on Galatians (1531) and Genesis (1535-1545). It reveals that Luther employed his unique understanding of Law and Gospel to inculcate in his students the understanding and desire to faithfully live out their callings in the vocations to which God had appointed them. He provided resources to do the same in the parishes they were to serve. Though in recent years the field of Luther studies has begun to appreciate the invaluable pastoral insights of this experienced master of pastors, the research has focused primarily on Luther's early works. Moreover, little attention has been given to exploring Luther's message as he cultivated an upcoming generation of pastors in his classroom. This work seeks to address this lacuna.
