It existed from the beginning of creation before Adam & Eve committed sin. It’s one of the first commandments YESHUA HIMSELF gave us:
1.Be fruitful and multiply and replenish the earth;
2.Subdue the earth;
3.Have dominion over all the earth including the fish, fowl and every living thing that move on the earth;
4.We can eat of every herb bearing seed and every tree in which is the fruit of a tree yielding seed;
5.Keep the Sabbath;
6.Do not eat of the tree of knowledge of good and evil;
It will exist after YESHUA’ second coming and even after the HIS final judgement was issued.

There are only a few requirements on how to spend YESHUA’ Sabbath:
1.Rest in YESHUA
2.Keep YESHUA’ Sabbath holy;
3.Don’t do any work;
4.Don’t be the cause that someone have to work;
5.Don’t do our own ways, our own pleasure or speak our own words;

It is a perpetual covenant; it is the mark/seal of YESHUA…of HIS authority…that HE is YHWE
