The problem is that the Pharisaical understanding of justification (being rendered innocent) is not what the scriptures teach. It's what the Pharisee's taught. It was their added teachings that Yeshua came against to correct in all of his dealings with the Pharisee's and other religious leaders at that time. He came against THEIR traditions added to the Law and Prophets, which was what YHVH had warned them not to do. (Deuteronomy 12:32) "Everything that I command you, you shall be careful to do. You shall not add to it or take from it."
The only way to be rendered innocent is by faith in Yeshua Messiah. It's how Abraham was justified. It's how Isaac was justified. It's how Moses was justified. Their faith in the salvation of YHVH (Yeshua) was accounted to them as righteousness. It was not their status as a Jew/Hebrew.
Yeshua said in Matthew 5: 17-19, "Do not think that I have come to abolish the Law or the Prophet; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches other to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven."
If you believe that the Pharisees are right, in that justification (being rendered innocent) only happened by their definition, then getting rid of the law seems like a logical solution and puts Yeshua back in his rightful place. If you don't agree with the Pharisees and look beyond their false teaching you can see that the Law never could render you innocent, BUT it also means according to Yeshua's own words, that the law then is still relevant. If it never was put in place as a means for justification (being rendered innocent), then it doesn't need to be gone. In fact Yeshua says that until heaven and earth pass away (they are still here in case you weren't sure) not one jot or tittle will pass from the Law until ALL is accomplished. Even still, Yeshua goes on to say that who ever doesn't do them and teaches others to "relax" them, will be called least in HIS kingdom.
It's not, either or (grace or law); its both and (grace and law).
I am rendered innocent by faith in Yeshua and show that I love him by calling on his grace as I follow His commandments, including the jot's and tittle's.
We all, Jew and Gentile, have access to the Father through Yeshua, and blessed be that gift.
My Saviour, how I love thee!
