Without the illumination of the moral Law, man is in darkness as to his true sinful condition in God’s eyes (see Rom. 7:7,13). The Law demands perfect righteousness (see Psa. 19:7). Even one transgression against its holy precepts will condemn us (see James 2:10), but in reality, the most righteous of human souls has a multitude of sins (see Jer. 30:15; James 5:20).
Ezekiel 33:12 “Therefore you, O son of man, say to the children of your people: ‘The righteousness of the righteous man shall not deliver him in the day of his transgression; as for the wickedness of the wicked, the shall not fall because of it in the day that he turns from his wickedness; nor shall the righteous be able to live because of his righteousness in the day that he sins.’13 When I say to the righteous that he shall surely live, but he trusts in his own righteousness and commits iniquity, none of his righteous works shall be remembered; but because of the iniquity that he has committed, he shall die.
