Mathesius with good spiritual taste says: "He who learns to know Christ in Genesis has instruction in the power of the divine Word and knows what sin and righteousness are, which avail before God. My testimony concerning this blessed Commentary I wish to leave behind me that my natural and spiritual children may not forget it, but esteem it highly all their lives. My Genesis, for the sake of instruction and consolation, I have frequently read through, underscored and described. Remember this commentary explained to me the Word and will of Christ, and from it God gave comfort, rest and life to my troubled soul. For when our case is like the suffering of the patriarchs and the exposition suits one's heart as if the Doctor really speaks with us, then the Commentary is incorporated in us and lives in us, and refreshes and quickens one's heart." Joachim Morlin, in "How to Read With Profit the Writings and Books of the Beloved and Blessed Man of God, Dr. Martin Luther," praises above all others this Commentary and says: "Read the following 'Consummatum Est,' 'It Is Finished,' of this holy man, 'The Beloved Genesis,' in which as in a new world he brings forth and opens up not only certain parts but all the treasures and riches of the wisdom of the divine Word, so that there is not another book like it on earth since the times of the apostles. Luther's Genesis makes all theologians scholars." Jerome Weller says: "Luther's Commentary on Genesis is his Swan Song. For although all Luther's writings are full of manifold doctrines and consolations, yet his Commentary on Genesis excels all others. There is hardly a temptation for which he has not given in this Commentary a sure remedy; yes, Luther has excelled himself in this Commentary. Therefore I continually admonish all theological students again and again that they read this commentary diligently and assiduously and never lay it out of their hands, but seek to be wedded to it. For I can assure you I received more benefit from this commentary than from almost all the other writings of Luther. Therefore I will never be satisfied nor tired of reading it. If all that has been written since the apostles were gathered in one heap, they would not be worthy to be compared with this Commentary. I know that I speak the truth, and all who have experienced the truth and learned theologians share my convictions."
