Answer: Saturday is the 7th day - the Bible Sabbath (and that makes Sunday -- week day 1 -- the first day of the week)
Yes.
Except you forget that the Sabbath was made for mankind. It was not something that Jesus was to be a type of, it was a memorial of Creation.
Let us understand why the Sabbath rest day was for the Israelites,
BUT...... NOT for Adam.
Adam was living in God's Sabbath perpetually. Do you understand, that Adam's every day, was within God's rest day.
Adam was made for God's Sabbath day.
Adam's rest day ended when he disobeyed God and then he was told that he would work by the sweat of his brow.
Adam no longer was made for God's Sabbath, because he was kicked out.
God in his mercy, seeing that man needed to rest, assigned a day, called the Sabbath, for the people of Israel. As Jesus said.......
This particular Sabbath given to Moses, was made for man, but not for the purpose of man made for the Sabbath. (Mark 2:27)
Adam, on the other hand was made for the Sabbath.
Do you understand the big difference?
Now, when Jesus was crucified and rose on the 1st day of the week, this day became the spiritual eighth day of the week.
This meant, that those in Jesus once again entered God's rest day, on the eighth day, whereby the fall in the Garden was repaired and now......
Those in Jesus Christ are of the last Adam, once again being made for the Sabbath.
Do you understand?
In conclusion, born again believers in Christ are living in God's Sabbath perpetually. Do you understand, that
OUR every day,
IS within God's rest day. We have been restored to the Garden status, where the breach has been restored and we are living perpetually within God's New rest day, in Christ Jesus.
That is why the apostle wrote.......
8Now if Joshua had given them rest,
God would not have spoken later about another day. 9So there remains a Sabbath rest for the people of God.
10For whoever enters God’s rest also rests from his own work, just as God did from His.
11Let us, therefore, make every effort to enter that rest, so that no one will fall by following the same pattern of disobedience. (Hebrews 4:8-11)
What prevented Adam from staying within God's rest day, was his works of disobedience. So the author in Hebrews states that another Sabbath rest day was appointed, for those who do not follow the works leading to a pattern of disobedience and who perpetually remain in Christ's eighth day rest.
The first day of the week is become the eighth day, where born again believers are once again made for God's rest day, as Adam was, before his fall.
