*****O.K.! Let's examine the silliness of your statement. [Genesis 2:2-3] and God completeth by the seventh day His work which He hath made, and ceaseth by the seventh day from all His work which He hath made. And God blesseth the seventh day, and sanctifieth it, for in it He hath ceased from all His work which God had prepared for making. *******
Well, lets look at Moses' statement and see why God gave THEM, not US, the Sabbath.
Deu 5:12 ¶ Keep the sabbath day to sanctify it, as the LORD thy God hath commanded thee.
Deu 5:13 Six days thou shalt labour, and do all thy work:
Deu 5:14 But the seventh day [is] the sabbath of the LORD thy God: [in it] thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that [is] within thy gates; that thy manservant and thy maidservant may rest as well as thou.
Deu 5:15 And remember that thou wast a servant in the land of Egypt, and [that] the LORD thy GOD brought thee out thence through a mighty hand and by a stretched out arm: THEREFORE the LORD thy God commanded thee to keep the sabbath day.
Now, WHY did GOD command THEM to keep the SABBATH day?
Read Deut 5:15 again.
And again,
The LORD our God made a covenant with us in Horeb.
Deu 5:3 The LORD made not this covenant with our fathers, but with us, [even] us, who [are] all of us here alive this day.
Easy:
Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labor, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exo 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
That's why. Because the Lord, Jesus Christ, made the heaven, earth, sea and all that is in it and BLESSED and MADE HOLY the sabbath day.
Show me where the Lord, Jesus Christ, ever UNBLESSED or made UNHOLY the sabbath day.
