The Ten Commandments are a summary of the Old Covenant
Exodus 34:28 “So he was there with the Lord forty days and forty nights. He neither ate bread nor drank water. And he wrote on the tablets the word of the covenant, the Ten Commandments.
Exodus 31:18 “And he gave to Moses when he had finished speaking with him on Mount Sinai, the two tablets of the testimony, tablets of stone, written with the finger of God.
Deut 4:13 “And he declared to you his covenant, which he commanded you to perform, that is, the Ten Commandments, and he wrote them on two tablets of stone”.
Deut 9:9 “When I went up the mountain to receive the tablets of stone, the tablets of the covenant that the Lord made with you.”
Deut 9:11 “And at the end of forty days and forty nights the Lord gave me the two tablets of stone, the tablets of the covenant.”
The Old Covenant was an agreement between God and Israel, not God and Christians
Ex 31:12-17 And the Lord said to Moses, “You are to speak to the people of Israel and say, ‘Above all you shall keep my Sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the Lord, sanctify you. You shall keep the Sabbath, because it is holy to you. Everyone who profanes it shall be put to death. Whoever does any work on it, that soul shall be cut off from among his people. Six days shall work be done, but the seventh day is a Sabbath of solemn rest, holy to the Lord. Whoever does any work on the Sabbath day shall be put to death. Therefore the people of Israel shall keep the Sabbath, observing the Sabbath throughout their generations, as a covenant forever. It is a sign forever between me and the people of Israel that in six days the Lord made heaven and earth, and on the seventh day he rested and was refreshed.”
The Old Covenant is no longer in effect for ANYONE
Heb 8:13-9:4 In speaking of a new covenant, he makes the first one obsolete. And what is becoming obsolete and growing old is ready to vanish away. Now even the first covenant had regulations for worship and an earthly place of holiness. For a tent was prepared, the first section, in which were the lampstand and the table, and the bread of the Presence. It is called the Holy Place. Behind the second curtain was a second section called the Most Holy Place, having the golden altar of incense and the ark of the covenant covered on all sides with gold, in which was a golden urn holding the manna, and Aaron’s staff that budded, and the tablets of the covenant.
Gal 3:17 This is what I mean: the law, which came 430 years afterwards, does not annul a covenant previously ratified by God, so as to make the promise void.
Gal 3:19 Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary.
Gal 3:24 So the law was our guardian until Christ came, in order that we might be justified by faith
Gal 3:25 But now that faith is come, we are no longer under a guardian
2 Cor 3:4-18 Such is the confidence that we have through Christ toward God. Not that we are sufficient in ourselves to claim anything as coming from us, but our sufficiency is from God, who has made us sufficient to be ministers of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life. Now if the ministry of death, carved in letters on stone, came with such glory that the Israelites could not gaze at Moses’ face because of its glory, which was being brought to an end, will not the ministry of the Spirit have even much more glory? For if there was glory in the ministry of condemnation, the ministry of righteousness must far exceed it in glory. Indeed, in this case, what once had glory has come to have no glory at all, because of the glory that surpasses it. For if what was being brought to an end came with glory, much more will what is permanent have glory. Since we have such a hope, we are very bold, not like Moses, who would put a veil over his face so that the Israelites might not gaze at the outcome of what was being brought to an end. But their minds were hardened. For to this day, when they read the old covenant, that same veil remains unlifted, because only through Christ is it taken away. Yes, to this day whenever Moses is read a veil lies over their hearts. But when one turns to the Lord, the veil is removed. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. And we all with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.
The Sabbath, as part of the Old Covenant, is not in effect for ANYONE
Gal 4:10 You observe days and months and seasons and years! I am afraid I may have labored over you in vain.
Rom 14:5-6 One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind.
Col 2:16-17 Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ
Jesus is our Sabbath or spiritual rest, and we enter into that spiritual rest by placing our faith in Him
Matt 11:28-30 Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and lean from me, for I am gentle and lowly in heart, and you will find rest for your souls.
Heb 4:1-8 Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it. For good news came to us just as to them, but the message they heard did not benefit them, because they were not united by faith with those who listened. For we who have believed enter that rest, as he has said, “As I swore in my wrath, They shall not enter my rest. “ although his works were finished from the foundation of the world. For he has somewhere spoken of the seventh day in this way: “And God rested on the seventh day from all his works.” And again in this passage he said, “They shall not enter my rest.”. Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience, again he appoints a certain day, “Today”, saying through David so long afterward, in the words already quoted. “Today, if you hear his voice, do not harden your hearts.” For if Joshua had not given them rest, God would not have spoken of another day later on. So then there remains a Sabbath rest for the people of God, for whoever has entered God’s rest has also rested from is works as God did from his. Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience.
Christians are under the New Covenant, which has much higher demands and different commandments
Luke 22:20 And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant in my blood.”
Heb 9:15 Therefore, he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.
Jn 13:34 A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.
Jn 15:12 This is my commandment, that you love one another as I have loved you.
Jn 15:17 These things I command you, so that you will love one another
Rom 13:10 Love does no wrong to a neighbor; therefore love is the fulfilling of the law.
