Ok, I answered this several times before, But let’s give it one more try. If you think that God was only talking to the ethnic Jews in Ex.31 not 21 by the way, then what do you do with Mark 2: 27 And he said unto them, The sabbath was made for man, and not man for the sabbath:
The two seem incompatable, right? We know or at least we should know that there are no contradictions in the bible. Well, let’s assumne that we know what is meant by man in Mark 2:27 That would mean that we have a faulty understanding of what is meant by Israelites or Jews. Consider Heb8
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
7 For if that first covenant had been faultless, then should no place have been sought for the second.
8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
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:
11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
The new covenant is made with the “the house of Israel and with the house of Judah” Wouldn’t that men the Jews? Does that mean that Jesus came only for the Jews? Of coarse not. So again we need to adjust our understanding of what “the house of Israel and with the house of Judah” means. So, let’s look at
Romans 9
4 Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;
5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.
6 Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:
7 Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.
8 That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
“they are not all Israel” What this is saying is all of those that are ethnic Jews are not necessarily children of God John1:12 but the children of the promise are. What does that mean? Well, this is the promise talked about.
Gen12
2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.
This blessing is of coarse Jesus Christ. So, you see when ex.31:13 Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the Lord that doth sanctify you.
The Sabbath has not ended at the cross in fact keeping God’s law is the mark of God’s end time remnant church.
Rev.12
17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Rev.14
12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
