Actually, I did address your post.
Sabbatarians will often argue that the Sabbath did not begin at the Exodus but at creation, and, therefore, cannot be a shadow of Christ, since the Sabbath came before sin. However, in the second giving of the Ten Commandments, the reason for keeping the Sabbath was to "Remember that you were slaves in Egypt and that the LORD your God brought you out of there with a mighty hand and an outstretched arm. Therefore, the Lord your God has commanded you to observe the Sabbath day." (Deuteronomy 5:15) Certainly God's deliverance of Israel from slavery foreshadows Christ's deliverance of believers from their slavery to sin.
Where did God command EVERYONE to keep the Sabbath on the seventh day?
If every man from Adam to Moses kept the Sabbath, why is the Hebrew word for the weekly Sabbath found in the Ten Commandments, never found in the book of Genesis? Why is no one before Moses ever being told to keep the Sabbath? Why are there no examples of anyone keeping the Sabbath before Moses? Why were the Patriarchs never instructed about the Sabbath, but were instructed regarding: offerings: Genesis 4:3-4, Altars Genesis 8:20, Priests: Genesis 14:18, Tithes: Genesis 14:20, Circumcision: Genesis 17:10, Marriage: Genesis 2:24 and Genesis 34:9. Why would God leave out the Sabbath command in Genesis if it was for everyone to keep before Moses? You are ignoring the CONTEXT of Mark 2:27 and are misinterpreting the words of Jesus.
As I previously explained, Jesus said, "the Sabbath was made for man," not all mankind. *I see that you completely ignored (Exodus 31:16-17; Deuteronomy 5:12-15; Nehemiah 9:13).
Your arguments and writing style sound very familiar. Have you been here before under a different avatar name?
BTW the Church is NOT under the Old Covenant. Sabbath keeping with all it's rules and regulations, was
part of a covenant with Israel (Exodus 16:23, 29; 31:12-18; 35:1-3; Leviticus 19:30; 23:2-3, 32; Numbers 15:32-36; 28:1-10; 29:39-40; I Chronicles. 23:30-31; II Chronicles 31:2-4; Isaiah 1:13; Amos 8:5; Nehemiah 10:31) that is
not binding on Christians under the New Covenant. (Colossians 2:16-17) The Bible nowhere describes The Church/Christians setting aside the Sabbath day as the day of worship. The only Scriptures that describe Christians meeting on the Sabbath are in fact pointing to evangelistic efforts at Jewish synagogues, which met on the Sabbath day.
