Let's look at your quote from the original sources. It turns out that it is actually snips from two different articles in two different periodicals. The first article is "Hold Fast the Faith" from
The Southern Watchman. The second article is "Our Work" from
The Review and Herald.
Just from the titles, we can gather that they focus on different things. But somehow, they both refer to the covenant made at Sinai.
The covenant that God made with his people at Sinai is to be our refuge and defense. The Lord said to Moses:-- {SW, March 1, 1904 par. 40}
"Thus shalt thou say to the house of Jacob, and tell the children of Israel: Ye have seen what I did unto the Egyptians, and how I bare you on eagles' wings, and brought you unto myself. Now, therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people; for all the earth is mine, and ye shall be unto me a kingdom of priests, and a holy nation." {SW, March 1, 1904 par. 41}
"And Moses came and called for the elders of the people, and laid before their faces all these words." {SW, March 1, 1904 par. 42}
"And all the people answered together, and said, All that the Lord hath spoken we will do." {SW, March 1, 1904 par. 43}
This covenant is of just as much force today as it was when the Lord made it with ancient Israel. {SW, March 1, 1904 par. 44}
What is "this covenant" that is "of just as much force today"? Who made this covenant? The text clearly says that God made this covenant. It is the covenant, in summary, to make His people a holy nation.
Why did she bring this up? Here's what she wrote just before this:
The people of God will conquer through the Holy Spirit's working, which is stronger than miracles or aught else. It is from the Lord that we are to obtain power. {SW, March 1, 1904 par. 39}
She was talking about how we are to conquer, how we are to obtain power. And how do we do that? By accepting His promise to make us a holy nation.
How was Israel's salvation effected? Was it because they were such a strong nation, a powerful people? No. It was because God saved them, in spite of themselves. "Ye have seen what I did unto the Egyptians, and how I bare you on eagles' wings, and brought you unto myself."
That covenant is in full effect today. The weakest of the weak can overcome if he allows God to save him. Today, as it was then, we can be freed from sin, not by our valiant efforts, but only as God frees us. This is how we are saved.
"Moses went up unto God, and the Lord called him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel: Ye have seen what I did unto the Egyptians, and how I bear you on eagles' wings, and brought you unto myself. Now therefore, if ye will obey my voice indeed,"--in truth, earnestness, and sincerity,--"and keep my covenant, then ye shall be a peculiar treasure unto me . . . for all the earth is mine: and ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel. {RH, June 23, 1904 par. 6}
"And Moses came and called for the elders of the people, and laid before their faces all these words which the Lord commanded him. And all the people answered together, and said, All that the Lord hath spoken we will do." {RH, June 23, 1904 par. 7}
This is the pledge that God's people are to make in these last days. Their acceptance with God depends on a faithful fulfilment of the terms of their agreement with him. God includes in his covenant all who will obey him. To all who will do justice and judgment, keeping their hand from doing any evil, the promise is, "Even unto them will I give in mine house and within my walls a place and a name better than of sons and daughters: I will give them an everlasting name, that shall not be cut off." {RH, June 23, 1904 par. 8}
Here, we find a different aspect of truth. There is work for us to do. Yes, we are to obey.
However, we do not obey in order for God to save us. We cannot obey unless God saves us first.
Our obedience, our pledge to do all He has spoken, is a loving response to what He has already done for us. Our obedience is not what makes the New Covenant effective. Rather, it is the New Covenant being effective that makes our obedience possible.
Further, our obedience is our "part" of the bargain if we are to
continue in the NC. This is where it could get confusing. Obedience is part of the NC, but not the means to effect the NC. It is the result of partaking of the NC.
In contrast, the OC required obedience in order to be saved. First you obey, then you live.
The NC, founded on better promises, is that you accept the life God is offering, then you obey.
