Ask yourself..........who is Moses speaking to? He is speaking to the Children of the original Israelites who are all now dead [Numbers 14:26-35]. The dead Israelites were the ones who received the Law of Yahweh at Horeb (Sinai) [Exodus, chapters 20 through 24]......(our fathers).
Moses is now explaining the second covenant given to the Isarelites....and he's doing it 40 years later....on the Plains of Moab [Deuteronomy 1:1-5]
The second Covenant includes things like the Levitical Priesthood [Numbers 3:11-13] which was not part of the first....the blessings and the curses which also did not appear until the Law of Moses [Deuteronomy chapter 28]. These two Covenants given to Israel were not the same:
[Deuteronomy 29:1] These are the words of the covenant, which the LORD commanded Moses to make with the children of Israel in the land of Moab, beside the covenant which he made with them in Horeb.
It is lack of knowledge that causes much confusion when discerning scripture. The reason you are not aware of this is because the Church has never taught it. If they were to teach this doctrine then people would logically ask...."Then the Law of Yahweh" ....the Ten Commandments were not part of the "Law of Moses"? And you would then reply......,"Yes, that's correct....and the Law of Moses with its sacrifices and regulations was changed [Hebrews 7:11-12].....but the Law of Yahweh with its fourth commandment....still stands!"
[Hebrews 10:4] For it is not possible that the blood of bulls and of goats should take away sins.
But now, let me ask you, DOES GOD CLOSE HIS EARS ON THE OTHER DAYS OF THE WEEK IF SOMEONE OFFERS PRAYERS OR HYMNS other than YOUR SABBATH?
If God does not close his ears on other days why are we having this discussion in the first place.
So, Go to your church on Saturday and sit in smug satisfaction that you are doing it “right” by keeping the DAY, and all others are doing it wrong.
I will go to church on Sunday where we will worship the Lord JESUS as Christians have done for the past 2000 years, and not worry about the day.
