Since therefore, as the text shows, Adam alone heard this sermon from God, it must have been preached to him on the sixth day, and Adam must have afterwards communicated it to Eve on the same day. And if they had not sinned Adam would have set this remarkable sermon or precept before his whole posterity also; and by it they would have become the most profound divines, the most learned lawyers and the most experienced physicians. Now there exists an infinite number of books by which men are trained to be theologians, lawyers and physicians. But all the knowledge we can obtain by the help of all these books together can scarcely be called the dregs of science, if compared with that fund of wisdom which Adam drew from this one sermon of God. So utterly corrupted are all things by original sin. This "tree of the knowledge of good and evil," therefore, or this place in which a number of trees like unto it were planted, would have been, as we have said, a church, where Adam and his posterity, had he and they continued in their innocency, would have assembled on the Sabbath day; and Adam, after refreshment derived from the "tree of life," would have preached God to those assembled, and would have praised him for the dominion which he had given them over all other creatures he had made. The 148th and 149th Psalms set forth a certain form of such praise and thanksgiving, where the sun, the moon, the stars, the fishes and the dragons are called upon to praise the Lord. But there is no one psalm so beautiful, but that any one of us might compose one far more excellent and more perfect, if we had been born of the seed of Adam in his state of original innocence. Adam would have preached that highest of all blessings, that he had been created in and that his posterity bore the image and the similitude of God. He would have exhorted them all to live a holy life without sin, to till the garden in which God had placed them with all industry, to keep it with all diligence, and to guard with all caution against tasting the fruit of the "tree of the knowledge of good and evil." This external place, form, worship and preaching of the Word, man would most certainly have observed on the Sabbath. Afterwards he would have returned to his duties of laboring and guarding until the time appointed of God had been fulfilled, in which he should be translated without any death and with all sweetness to heaven.
