Hebrews explains how Jesus' sacrifice has fulfilled (kept, satisfied, etc...) various first covenant laws so that they are no longer recurring obligations for God's people to perform. Jesus' work on the cross is so thorough, so complete, and so everlasting that no debt of law in regard to those things remains. So those laws no longer have to be literally carried out by the followers of God.
Our faith in Jesus' work on the cross has, in effect, fulfilled the first covenant laws for sacrifice, temple, and priesthood. Those laws were made obsolete (no longer needed--not destroyed) for a people perfectly and forever cleansed and brought near to God through the sacrifice and ministry of Jesus. That is the fulfillment Jesus said must happen before the least stroke of a pen could disappear from the law. And now the remaining debt of law we owe is "love your neighbor as yourself" (see Romans 13:8-10). And even that is fulfilled (kept, satisfied, etc.) through our faith in God's forgiveness as we give the love we ourselves have received from God to our neighbor. Amen, amen, and amen.

I think only the wrath/condemning part of the law is finished,but not all of the law as the wrath/condemning part of the law was against us.
Romans 4:15:Because the law worketh wrath: for where no law is, there is no transgression.
Romans 5:16:And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification.
Romans 5:18:Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life.
Romans 8:1:There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Romans 5:9:Much more then, being now justified by his blood, we shall be saved from wrath through him.
1 Thessalonians 5:9:For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ,
Since the wrath/Condeming part of the law was against....that was done away with as been nailed to the cross.
Colossians 2:14:Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
The wrath/Condemning part of the law in the OT for example...

Exodus 22:!9:Whosoever lieth with a beast

If we have no law then we are very lawless people....
