A more sure word of prophecy

Yet with the living oracles before them, those who claim to preach the word present the suppositions of human minds, the maxims and commandments of men. They make void the law of God by their traditions. The sophistry in regard to the world’s being created in an indefinite period of time is one of Satan’s falsehoods. God speaks to the human family in language they can comprehend. He does not leave the matter so indefinite that human beings can handle it according to their theories. When the Lord declares that He made the world in six days and rested on the seventh day, He means the day of twenty-four hours, which He has marked off by the rising and setting of the sun. TM 135.3

God would not present the death sentence for a disregard of the Sabbath unless He had presented before men a clear understanding of the Sabbath. After He had created our world and man, He looked upon the work that He had done, and pronounced it very good. And when the foundation of the earth was laid, the foundation of the Sabbath was laid also.“When the morning stars sang together, and all the sons of God shouted for joy,” God saw that a Sabbath was essential for man, even in Paradise. In giving the Sabbath, God considered man’s spiritual and physical health. TM 136.1
