Genesis 2:1 Thus the heavens and the earth were finished, and all the host of them. 2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. 3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
There are serious problems with the perspective put forth by so many contemporary Christians, that the Sabbath was given to the Jews only, as we will discover, when reading the Bible, line upon line and precept upon precept. First of all, the 7th day Sabbath was given to the human family in Eden, when there wasn’t a single Jew around. Adam wasn’t a Jew, neither was Noah, yet they both kept all of God’s commandments including the 7th day Sabbath.
Even though the law was hand written by God at Mt. Sinai, that does not necessarily mean that it was nonexistent up until that time. Just because something isn’t written does not mean to say it does not exist, and therefore, if God’s laws were not binding in Eden, Adam and Cain could not be guilty of any sin for sin is the transgression of the law. It becomes obvious, from a study of the Bible that the ten commandments were handed down from generation to generation by word of mouth.
Genesis 39: 7 And it came to pass after these things, that his master's wife cast her eyes upon Joseph; and she said, Lie with me. 8 But he refused, and said unto his master's wife, Behold, my master knows not what is with me in the house, and he hath committed all that he hath to my hand; 9 There is none greater in this house than I; neither hath he kept back anything from me but thee, because thou art his wife: how then can I do this great wickedness, and sin against God?
Genesis 4: 6 And the Lord said unto Cain, why are you wroth? and why is thy countenance fallen? 7 If you do well, shalt you not be accepted? and if you do not well, sin lies at the door. And unto thee shall be his desire, and thou shalt rule over him.
May God add His blessing to the study of His word. “Good night” and God bless!
