We are no longer under the law..the saved are under grace.. the law was OT ... The new testament is clear..the PURPOSE of the law was to show us we are sinners in need of a savior ...
Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin. (Romans 3:19-20)
Before this faith came, we were held prisoners by the law, locked up until faith should be revealed. So the law was put in charge to lead us to Christ that we might be justified by faith. Now that faith has come, we are no longer under the supervision of the law. (Galatians 3:23-25)
Gal 3:9 18For if the inheritance is based on law, it is no longer based on a promise; but God has granted it to Abraham by means of a promise. 19Why the Law then? It was added because of transgressions, having been ordained through angels by the agency of a mediator, until the seed would come to whom the promise had been made. 20Now a mediator is not for one party only; whereas God is only one. Jesus is that seed He fulfilled the law ..
Romans 3:28
For we maintain that a person is justified by faith apart from the works of the law.
The purpose of the law was to show us we need a Savior Romans 7:7
What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, “You shall not covet.”
