Before*I say any thing, I just wanted to make clear that I haven't read any other posts at all except the very first one.
The answer to your question in neither. The purpose of the Messiah was to take the place of the sacrifical law (the same thing as the law of righteousness) And my proof is all over Heb.10. (KJV) In order to understand most of what's happening in this chapter, you have to start reading at the beginning (Please read this on your own, preferably out of the KJV). I'm only going to put verses 6-10 KJV to save time:
*[[Heb 10:6-10/KJV]]*
*%v 6% In burnt offerings and sacrifices for sin thou hast had no pleasure.
%v 7% Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.*
%v 8% Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;*
%v 9% Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.*
%v 10% By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
Read verses 9 and 10 again. 9 said he taketh away "the first". But what is " the first"? The first is the law that was talked about in verse 8, the sacrifical law. "The second" is the Messiah, which is proven in verse 10.
Before the Messiah, (or since Adam and Eve), the wages of sin was death (Rom. 6:23). That's why every time someone sinned, instead of them dying they had to make a sacrifice. God was tired of constantly having to accept these offerings and sacrifices and put in place his son to be the ultimate sacrifice, the final sacrifice for everyone's sins.
This doesn't mean you cannot sin any more, but that's a different topic.
I hope I was clear in explaining and please read this on your own (KJV).
Also, forgive me if there are any typos for I am trying this without a keyboard.
