I am not entirely sure I understand what do you mean by this?
The ten commandments already existed before Moses.
The reason that the Israelites were taken out into the desert after Egypt also included what I suppose we would call a re education excursion. You have to remember, the Israelites had been in Egypt for many generations…they were corrupted by the Egyptian way of life and had largely forgotten their own heritage and belief structure.
When God took them to mount Sinai and gave them the 10 commandments, this was part of that process to remind them of what it mean to follow the one true God and not the idols and ways of Egypt.
Some might ask, how can I provide evidence that the 10 commandments already existed? That is quite easy…(I am not arguing allegory or otherwise below…that is not my intention here)
Genesis 12:16
16 And the LORD God commanded him, “You may eat freely from every tree of the garden, 17 but you must not eat from the tree of the knowledge of good and evil; for in the day that you eat of it, you will surely die.”
So here we have God saying to Adam, if you do not follow my expectations, my wishes, my laws, then you will surely die
then there are some interesting statements in the 10 commandments (and this is why the Sabbath commandment for example, is so important)
Given the Israelites had just left the Egyptian culture and its influences, dont you find it rather ironic that God starts off the 10 commandments as follows:
1 And God spoke all these words:
2 “I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery.
Then he goes on to say shortly after this:
8 Remember the Sabbath day by keeping it holy. 9 Six days you shall labor and do all your work, 10 but the seventh day is a Sabbath to the LORD your God, on which you must not do any work—neither you, nor your son or daughter, nor your manservant or maidservant or livestock, nor the foreigner within your gates. 11 For in six days the LORD made the heavens and the earth and the sea and all that is in them, but on the seventh day He rested. Therefore the LORD blessed the Sabbath day and set it apart as holy.
It is very obvious that the law, Gods eternal law, pre existed this earth we live on. That should make perfect sense to any Christian to be honest and here’s why: A person, a mature adult person, has beliefs that they inherited from their upbringing. These things usually a result of indoctrination from parents, peers and culture. Now God is accepted by Christians as being a mature adult…the difference being, he was never a child who had to learn from anyone. Now that we have established the everlasting nature of God, it should be quite easy to theologically accept that God has rules and these rules are as old as He is.
Rules are not a consequence of sin, that is a complete fallacy. Science has rules, do these rules only exist because of failure or do they exist because they are a natural order of things? Is natural order sinful? I would argue it is not!
the point of law is to provide a pathway to maintain harmony. If we follow that pathway, we stay safe…if we venture off it, then chaos erupts. That is the natural order of things…in an of itself, it isn’t sinful or evil any more than laws are. We do not say that the law the criminal breaks is sinful, we say the criminal who refuses to follow the natural order of things (ie the law) is sinful.
So even within our every day lives experience, it should be quite easy to understand and accept that the 10 commandments, Gods law of Love, predates Exodus 20 and even creation. It also means that these laws will continue to exist for as long as God does…all eternity.
