As usual, you have no idea what you're talking about. Someone who sits on the fence between law and grace uses the law "unlawfully"...preaching it was made for the righteousness man and not for sinners. They have no idea the purpose of the law is fulfilled in us when we believe in the Lord Jesus Christ. You, for example, use the law unlawfully, by insisting righteousness comes from keeping the commandments. Don't even try to deny it....it's what you preach, even while you deny it (hypocrite). The law is for exposing sin and to bring us to Christ....and can never give life, in and of itself.
1 Tim. 1:7-10
Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm. But we know that the law is good, if a man use it lawfully; Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;
