Hebr 10:
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;
9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.

Hebr 7:
11 ¶ If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
12 For the priesthood being changed, there is made of necessity a change also of the law.

The Bible teaches that the change of the law cancelled the order of the Old Covenant. The Lord Jesus did not destroy God's law (the Ten Commandments). The Lord Jesus and order of the New Covenant canceled animal offerings, death sentences, commands of temple service and all commands that don't agree with the Ten Commandments. The Ten Commandments are still in the power in the era of the New Covenant.

The commands of the Old Testament that have mentioned to be valid in the New Covenant are also power in the New Covenant. For example, prohibition to eat blood is still power in the New Covenant, because the New Testament mentions it to be valid in the New Covenant; the New Testament teaches and mentions that homosexuality is a sin, so it is also power in the New Covenant. Of course also those teachings that the New Testament teaches that isn't mentioned in the Old Testament are also in the power in the New Covenant.

In the New Covenant isn't in the power a command of death sentence. New Covenant congregation cannot judge or condemn anyone to death. Stoning is not in the power at the time of the New Covenant. Old Testament's "slave" wasn't the slaves, but servants and Israelites had to treat them well.

In the era of the New Covenant majority of the commands of the Old covenant is not in the power. Ideas of mockers, who say that you should keep all 613 commandments in the era of the New Covenant are pointless and foolish. It is as foolish as if someone would demand that people must punish in public places by stocks or pillory. Here in Finland where I live, stocks and pillory penalties had been annulled in 1894.

All the commands of the New Testament have been placed in a certain phase of history, but by Jesus' atonement is placed the New Covenant and the new order how to believe in God. You can't go back to the order of the Old Covenant, because it is not anymore in the power. In the same way stocks and pillory penalties are not anymore in the power, and it is very foolish and absurd demand to punish people with stocks and pillory. As foolish is to demand to obey those commands of the Old Covenant that are no longer in the power.
