"God did not sanctify to himself the heaven nor the earth nor any other creature. But God did sanctify to himself the seventh day. This was especially designed of God, to cause us to understand the seventh day is to be especially devoted to divine worship. For that which is appropriated to God and exclusively separated from all profane uses is sanctified or holy... It follows therefore from this passage, that if Adam had stood in his innocence and had not fallen he would yet have observed the "seventh day" as sanctified, holy and sacred; that is, he would have taught his children and posterity on that day concerning the will and worship of God. Further by this sanctification of the Sabbath it is also plainly shown that man was especially created for the knowledge and worship of God. For the Sabbath was not instituted on account of sheep or oxen, but for the sake of men, that the knowledge of God might be exercised and increased by them on that sacred day. Although therefore man lost the knowledge of God by sin, yet God willed that his command concerning the sanctifying of the Sabbath should remain. He willed that on the seventh day both the Word should be preached, and also those other parts of his worship performed, which he himself instituted; so the end that by those appointed means we should first of all think solemnly on our condition in the world as men; that this nature of ours was created ...for the knowledge and the glorifying of God; and also that by these same sacred means we might hold fast in our minds the same hope of a future and eternal life."
