God has finished creating everything. His work was finished and now He does three things.
1. He rests, not in the physical sense but rather He ceases the activity of creation and now creation could produce and reproduce without being recreated.
The interesting thing about the word rested “Shebat”here is that it forms the root word for Sabbath.
2. He blesses this day of rest
3. He sets it apart and makes it holy “Kadosh.” God can only make something holy. We can acknowledge that something is holy but we cannot declare anything holy.
Some like to argue whether man needs to worship on the Sabbath (Saturday) or what we call the Lords Day (Sunday). The Hebrew people still worship on Saturday, as well as Seventh Day Adventists. Christian groups worship on Sunday, or the first day of the week, since that is when the Apostles gathered.
Others like to argue that the Council of Laodicea, who gathered in the 4th century to discuss doctrine,changed history in significant ways. In this council, the early Church fathers determined what would and would not be considered canon and they decided what would and would not be included in the Bible or read at church.
During the 2nd and 3rd centuries, Christians were in the habit of keeping both Saturday and Sunday. In fact Ethiopian Christians still do today. During that time, Christians rested on the Sabbath (in the Lord) and had communion or fellowship on Sundays. The Church fathers at the Council of Laodicea were not opposed to Sunday services but were opposed to Christians Judaizing the Sabbath. Judaizing is what they labled Christians resting on the Sabbath day. At the Coucil of Laodicea, they published as doctrine that the practice of staying at home and resting on the Sabbath was sinful and anathema to Christ.
CHRISTIANS must not judaize by resting on the Sabbath, but must work on that day, rather honouring the Lord’s Day; and, if they can, resting then as Christians. But if any shall be found to be judaizers, let them be anathema from Christ.

During this time the Romans already worshiped the sun god on Sunday and called it the lords day.
What really matter is that God designed humans with the need for rest, regardless of what day it is on. I think we learn here that God gave man a day of rest, and we need to have one in order to function and keep our bodies in shape. We are no longer under the Law, in terms that we need to follow them to the letter, rather our rest comes from Jesus Christ. In His rest, we cease from everything that needs to be done for our salvation. That everything was done and finished in Jesus Christ forever.
