Why I break the law

[LUKE2447]

Also Jesus walked according to the Written Law of Moses and proved his righteousnes thus a proper sacrifice for us. So if Jesus had to be right before God to be a proper sacrifice and we are to emulate him which is in summary fullfill

Mar 12:29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord:
Mar 12:30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
Mar 12:31 And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.

Then why keep acting like the OT is a plague when it revealed truths of God. A light unto us? Messiah was the Torah/LAW/Word/Nature/Mind of God made known/revealed/manifested unto us. The reason he was able to meet the requirements of the law was because who can better fullfill the desire and chararcter of God unto his people than God himself in flesh?
