Correct, there are 613 Commandments.
Which include laws of cleanliness, holiness, sacrifice, paternity, marriage, divorce, etc.
Here is the thing no one person can keep all 613, not even the Messiah. Now, does that make the Messiah a sinner, HEAVENS NO! Among the 613 Commandments there are specifications as to which laws apply to which individuals.
For instance there are commandments that only apply to men, some only to women.
There are laws strictly for children, sons, and daughters.
There are laws for Fathers, and laws for mothers.
There are laws strictly for Priests, Kings, Judges, and Elders.
There are Commandments strictly for Farmers.
See, no ONE person can fit into ALL of there categories. So, a King is not breaking the Law(sinning) if he does not keep the commandment given to a Priest. Neither a Father who does not keep a commandment given only given to women. When you really look at the Commandments of G-D and you examine where you fall you see which commandments you are supposed to keep as servant of the Messiah, in Covenant with G-D the Father, an adopted child of G-D, and a wild Olive Branch grafted into the Cultivated Olive Tree of Israel to whom the New Covenant is given.
More or less, on average, each believer is responsible for keeping about 200 Commandments of the 613.
Think that's a lot? There are more traffic laws on the books, alone, in the United States than there are commandments of G-D given to all Covenant believers.
Commandments are not salvational. The Law can not and could never bring salvation. To say the commandments grant salvation is to make salvation based on works, which is obviously unattainable just as scripture bears witness. The Law is never meant to be kept FOR salvation, it is kept BECAUSE of Salvation. The Law is not for Salvation. The Law is for Sanctification, being set apart, made holy, and for training in Righteousness.
This is the same redundant accusation that is made to "Law-keepers" that we are somehow trying to "earn" our Salvation. Such is absurd! A total lie! A fabrication forged from the hearts who have misunderstood the writings of Paul, the Message of Scripture, the Power of The Gospel, and the center of the Covenant made with G-D and HIS people.
