I think many people misunderstand the law (of the Lord). The purpose of the law, I believe, was to show us what types of behavior get us into trouble. God gave us the law for our own benefit. For example: If I rob a bank, I'll probably go to prison. Therefore, the Lord told us not to steal. He didn't want to us to suffer. It isn't always as obvious as that, but I think the principle always holds. The law is our friend, not our enemy.
God gave the Hebrews 3 specific things - Neh 9:14
* Laws - specific to Hebrews were orally taught, then written, then copied, then distributed among the Hebrews, then the Tribes.
* Statutes - written Commands of God, first written BY Gods finger on stone tablets. The tablets broken by Moses. Rewritten by Moses on new tablets of stone.
* Precepts - behaviors among men, such and such behaviors for a good result. Such and such behaviors for a negative result.
OT study benefits any man, Because the Laws of the Hebrews, contains the History of the Hebrews & Tribes Relationship WITH God..
Additionally Gods Statutes and Gods Precepts are intermingled within Hebrew Laws.
The Laws, did not, do not apply to Gentiles.
The Statutes - apply to any man who believes in God.
The Precepts - apply to any man regardless if they believe in God.
NT study benefits any man, Because it reveals the Fulfilling of the Hebrew Laws; when, how, why, and the benefit of any man who Accepts the fulfillment.
Precepts - continue to apply regarding Behaviors among/between men...
Regardless of a mans relationship with or without God.
Confusion results in misunderstanding.
A mans relationship with God, is sealed in Conversion. Period. Sin against God has been overcome.
A mans relationship with man, IS NOT SEALED. Men are not all knowing, not all in agreement. Not all in one accord. Have differences. Bump against each other.
And when one man oversteps into an other mans SPACE, that is called a TRESPASS....but men as arrogant as they are....confuse;
Man against mans TRESPASS, as a SIN of man against man.
Mans SIN, is being Against God.
Mans TRESPASS, is man overstepping into an others mans Space, belongings, property, etc.
