Man in the fallen state is unable to keep the commandments perfectly. In fact, the commandments rebuked him. It shows him how incapable he is to keep it when he makes a truthful assessment by God’s standard. Jesus did not introduce the Law to show the young man how to be saved but to show him that he needed to be saved. The Law is like a mirror that reveals who we are (James 1:22), sinners through and through before we are saved.
