The carnal mind will fight against what I am going to present.
The end result is the same for those who are under the law and those who are without the law.
“For there is no respect of persons with God. For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;” (Romans 2:11-12)
If a person is under the law, they are making the law their authority without hearing the voice of the Giver. They are only hearing their own voice interpreting what the law means according to their carnal mindset of works without faith.
If a person has no law to observe, they also cannot hear the voice of the Giver, but are forced into hearing only what their voice is saying concerning right and wrong, claiming faith without works, which is a dead faith.
When the voice of God is heard, then God is the authority and not the law, even though the law still remains intact, and they are also under the grace of the Giver by faith.
“Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.” Matthew 5:17
According to the Aramaic language, (which was spoken at the time) this verse is better understood as follows.
“Think not that I am come to loosen, or release, (ashrea אשרא) the law, or the prophets: I am not come to unravel , but to complete (amala אמלא).
Being under the law is using the law as one's own authority with no grace obtained from the Giver. Throwing the law away also forces the individual to be one's own authority claiming grace from a Giver that they cannot hear. The end result is the same and both can be labeled as Pharisaical traditionalists.
When a man and woman are married via a marriage contract, and the woman goes to serve another man, as Israel went to serve other gods, then a divorce will occur. That doesn't negate the attributes of the husband, for his code of life remains the same. The Old Covenant can be completed, and incorporated into the New, but the Old Covenant cannot contain the New Testament in Christ in order to make the Old Covenant perfect.
“For if that first covenant had been faultless, then should no place have been sought for the second.” Hebrews 8:7
The writer of Hebrews proves by the testimony of Jeremiah, that there is a second testament or covenant, and therefore that the first was not perfect, and can only be completed by Christ Jesus.
