While occupied thus in delivering simple and practical sermons to his congregation in the town, he continued to publish written works of the same character and purport, in addition to his labours in the field of learned ecclesiastical controversy, thus showing the love with which he worked for them at large in this matter. These writings were little books, tracts, so-called sermons. It did not disturb him, he once said, to hear daily of certain people who despised his poverty because he only wrote little books and German sermons for the unlearned laymen. 'Would to God,' he said, 'I had all my life long and with all my power served a layman to his improvement; I should then be content to thank God, and would very willingly after that let all my little books perish. I leave it to others to judge whether writing large books and a great number of them constitutes art and is useful to Christianity; I consider rather, even if I cared to write large books after their art, I might do that quicker, with God's help, than making a little sermon in my fashion. I have never compelled or entreated anyone to listen to me or read my sermons. I have given freely to the congregation of what God has given to me and I owe to them; whoever does not like His word, let him read and listen to others.' In this spirit he composed, after the Leipzig disputation, a little consolatory tract for Christians, full of reflection and wisdom. He dedicated it to the Elector, an illness of whom had prompted him to write it. Even his most bigoted opponents could not withhold their approbation of the work. Luther's pupil and biographer Mathesius, thought there had never been such words of comfort written before in the German language. In a similar strain Luther wrote about preparation for dying, the contemplation of Christ's sufferings, and other matters of like kind. He explained to the people in a few pages the Ten Commandments, the Creed, and the Lord's Prayer. At the desire of the Elector, conveyed to him through Spalatin, and notwithstanding the difficulty he had in finding time for such a large work, he applied himself to a practical exposition of the Epistles and Gospels read in church, intended principally for the use of preachers.
