given that God does not make mistakes, he does not delegate his authority, he is eternal and most importantly, Gods satutes and laws are eternal...
Exodus 20
8Remember the Sabbath day by keeping it holy. 9Six days you shall labor and do all your work, 10but the seventh day is a Sabbath to the LORD your God, on which you must not do any work—neither you, nor your son or daughter, nor your manservant or maidservant or livestock, nor the foreigner within your gates. 11For in six days the LORD made the heavens and the earth and the sea and all that is in them, but on the seventh day He rested. Therefore the LORD blessed the Sabbath day and set it apart as holy.
exactly how do you come to this conclusion and what text in the Bible pray tell, do you use where the eternal omnipotent and all knowing God said, Sunday or indeed any day of the week is the Sabbath? (i would remind you before you answer to also consider which day was expressly set aside as a day of rest, sanctified and hallowed)
please quote me the bible verse where every day of the week has been set aside for worship and sanctified (Gen 2:3) and hallowed. Might pay to also revise what the term sanctified means btw and why this is relevant
A final thought before i end this post, the Sabbath was and institution of creation...it did not come about as a result of sin. So the idea that the Sabbath was done away with at the cross (because the wages of sin is death had been paid by Christs sacrifice) is not evidence in support of the removal of the institution of the Sabbath nor does it provide any statement changing the day or adding days for that matter. People incorrectly tie in the Sabbath with the law in such a way as to make the claim its an institution that is completed with the plan of Salvation. This is false...it’s a creation event. A time to worship our creator...it’s not a "thou shalt" rule...it is far more important than dealing with the corruption of sin. It is a relfection of the fact that we were created, a special day to worship our creator. Sin is not why the Sabbath exists! I find it interesting that Theistic Evolution at its very core, denies a literal seven day creation...this is denying the Sabbath...denying the special day of worship set aside by our creator for communion with Him. It is also very interesting that the Sabbath commandment is the bridge between loving God (commands 1-3) and loving thy neighbour (commands 5-10). We know that Jesus is the bridge between the sinful us and heaven. He is our salvation...our ticket. This is exactly why the Sabbath is a crucial doctrine for salvation. It does not mean one who doesnt keep the Seventh Day Sabbath could not possibly go to heaven...we are all sinners and break the commandments daily. However, this is why the apostle stated, "I die daily" (1cor 15:31). He needed to as do we all!
