The law of God is written in the hearts and mind of those who are under the new covenant.
Heb 8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
One of those law, one of those commandments written in the hearts of those who follow Christ is the 4th commandment:
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.
The sabbath is the Lord's sabbath.
The real meaning of the sabbath was discussed in the third and fourth chapters of Hebrews.
It certainly is. And Hebrews 4:9 says there still remains a sabbath keeping for the people of God.
Your original post certainly drew some, to be gentle, less than studied comments.
From what the apostle writes in both chapter three and four of Hebrews he seems to be saying that the 7th. day of Genesis 22:2&3 was still running when the Israelites were made to wander the wilderness and was still running in Paul’s day. Then a statement of his point in Hebrews 2:10 that we enter into that Sabbath resting by desisting from our own works and dong God’s will. Hence it seems the apostle is saying that that last “day” of Genesis hasn’t ended yet. Perhaps explaining why Jesus was “Lord of the Sabbath”. I’d enjoy hearing your thoughts on the matter.
