In an effort to settle the Sabbath question, with the Sabbath entirely left out (which would vitiate the whole law), a contributor to a local contemporary quotes Neh. 9: 13, 14, and then says:—
Now, these verses tell us, beyond the shadow of a doubt, that God first made known unto them His Sabbath at Sinai, by the hand of Moses. If they had already known it, there would have been no need for Him to make it known to them.
We will not assume that the writer of that comment never read Exodus 16; there is no doubt that he was familiar with the record there, and knew that the Sabbath was not first made known to Israel at Sinai. Moreover, the act of making known the Sabbath surely implies its previous existence. It would be just as logical to argue that the true God did not exist until He was made known to a class of people whose apostasy had separated Him from their knowledge, or that there was no Saviour of mankind until Jesus of Nazareth was made known by John the Baptist. Are we to suppose that there is no need to again make known the way of truth to those who have lost the way?
Yes, God caused all the typical sabbaths to cease, but His own memorial Sabbath was not typical. It was established at creation, before the fall, when as yet there was no occasion for types and shadows and ordinances. Gen. 2: 2, 3. The law of ordinances was repealed (Eph. 2: 15), but the law of Ten Commandments, of which not a jot or tittle could be changed (Matt. 5: 17, 18), makes no mention of ordinances. Under the new covenant it is written in the hearts of God's people. Jer. 31: 31-33. The Sabbath of the Lord is never called "their Sabbath," or "your Sabbath," only as they would make it theirs by profaning it. Otherwise God calls it "My Sabbath," or "My holy day," and it will endure, with the name of Israel, even in the new earth. Isa. 66: 22, 23. It will be a sign between God and the children of Israel throughout their generations, and that will be everlasting. Matt. 19: 28. All of God's people are Israel. The Gentiles, or unbelievers, are grafted into the old spiritual root by faith in Jesus Christ. See Rom. 11: 13-27.
The Sabbath question, or any other question, can not be settled by ignoring the law of God.
