Martin Luther’s chief pastoral concern was that his people would know Christ and His gospel. To this end, Luther carried on a profoundly deep practice of intercessory prayer. He said:
Open your eyes and look into your life and the life of all Christians, particularly the spiritual estate, and you will find that faith, hope, love … are languishing…. Then you will see that there is need to pray throughout the world, every hour, without ceasing, with tears of blood.
Luther’s pastoral heart is seen not only in his prayers but most notably in his preaching. He was a doctor of the church, a professor, and an academic. In his role as a professor, his primary task was to teach. There is a clear difference between teaching and preaching. The teacher instructs; he imparts information to his students. But a theologian/preacher can never sever the two roles of teacher and preacher. The great teacher/preachers of history never taught as mere isolated spectators of the past. They combined exhortation with instruction—inspiration with education. In a word, at times their teaching turned to preaching. In like manner, the scholar/pastor mixes teaching with his preaching.
Luther mirrored this method in his preaching. He was concerned to inform his congregation as well as to exhort it. He insisted that his messages should be clear and simple enough that the unlearned could understand them. He said:
Infinite and unutterable is the majesty of the Word of God…. These words of God are not words of Plato or Aristotle, but God himself is speaking. And those preachers are the most suitable who very simply and plainly, without any airs or subtlety, teach the common people and youth, just as Christ taught the people with homespun parables.
The gospel, the gospel… all for the gospel. This is the love, the task, the vocation of all who wear the robes of the theologian and all who wear the gowns of the preacher. Luther was equally comfortable attired in either.
