Q 96. What particular use is there of the moral law to unregenerate men?
A. The moral law is of use to unregenerate men, to awaken their consciences to flee from wrath to come,1 and to drive them to Christ;2 or, upon their continuance in the estate and way of sin, to leave them inexcusable,3 and under the curse thereof.4
Psalm 51:13
Then I will teach transgressors your ways,
and sinners will return to you.1 Timothy 1:9-11
understanding this, that the law is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for those who strike their fathers and mothers, for murderers, the sexually immoral, men who practice homosexuality, enslavers, liars, perjurers, and whatever else is contrary to sound doctrine, in accordance with the gospel of the glory of the blessed God with which I have been entrusted. (ESV)

For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
Romans 2:15
They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them (ESV)

For all who rely on works of the law are under a curse; for it is written, “Cursed be everyone who does not abide by all things written in the Book of the Law, and do them.” (ESV)
