The Lord Jesus said that He was the telos of the law. Not the cessation of law but the goal of the law. Paul writes in Galatians of the pedagogical use of the law to bring us to Christ. But there are other uses including the civic use (the civil magistrate is to punish bad guys) and the Christian's use for sanctification; that is to be holy or at least pursue holiness. In the latter Christ is the Holy one and a life that is a delight to Him is one of faith and holiness according to the law, which is His very own holiness.
For it is by grace you have been saved, through faith--and this is not from yourselves, it is the gift of God--
