Romans 3:19-20

19Now we know that whatever the Law [of Moses] says, it speaks to those who are under the Law, so that [the excuses of] every mouth may be silenced [from protesting] and that all the world may be held accountable to God [and subject to His judgment].

20For no person will be justified [freed of guilt and declared righteous] in His sight by [trying to do] the works of the Law. For through the Law we become conscious of sin [and the recognition of sin directs us toward repentance, but provides no remedy for sin].
